The carbon dioxide (CO2) surgical laser has been available in veterinary medicine for decades, but its adoption in general practice has accelerated as equipment costs have come down and continuing education resources have expanded. The 2026 Veterinary Laser Surgery Symposium (VLSS), held May 15–16 in Las Vegas, featured board-certified surgeons, dermatologists, and general practitioners presenting case-based guidance for integrating CO2 laser surgery into everyday practice — a signal that the technology has moved from early adopter to mainstream consideration.

This article covers what CO2 laser surgery is, what procedures it supports, how to evaluate equipment, what safety requirements apply, and how to decide whether it fits your practice.

The short answer

A CO2 surgical laser emits a focused beam of infrared light at a wavelength of 10,600 nm that is strongly absorbed by water in soft tissue. This allows the surgeon to cut, ablate, vaporize, and coagulate tissue with high precision while simultaneously sealing small blood vessels, nerve endings, and lymphatic channels. The result is less intraoperative bleeding, reduced postoperative pain and swelling, lower risk of infection (the laser superheats tissue at the incision site), and often faster recovery. Common veterinary applications include feline onychectomy, stenotic nares correction for brachycephalic breeds, skin mass removal, oral surgery, and dermatologic procedures. Equipment costs typically range from $10,000 to $30,000 depending on power output and features.

CO2 laser vs. cold-laser therapy: not the same thing

The distinction matters because the two technologies share the word "laser" but serve entirely different clinical purposes.

• CO2 surgical laser — a high-power device (typically 10–40 watts) that cuts, ablates, and coagulates tissue during surgical procedures. It replaces or supplements a steel scalpel. This is an invasive tool used in the operating room.

• Cold laser (low-level laser therapy / photobiomodulation) — a low-power device (typically 0.5–10 watts) that uses red or near-infrared light to reduce pain and inflammation and promote tissue healing through photobiomodulation. It does not cut tissue. This is a non-invasive therapeutic modality used in exam rooms and rehabilitation settings.

A practice that already offers cold-laser therapy has not added surgical laser capability. The equipment, training, safety protocols, and clinical applications are entirely different. This article focuses on CO2 surgical lasers only.

How CO2 laser surgery works

The CO2 laser produces a beam of light at 10,600 nm. At this wavelength, water — the primary component of cells — absorbs the energy efficiently. When the beam contacts tissue, the water in the cells vaporizes instantly, effectively cutting or ablating the tissue while the thermal effect seals adjacent blood vessels and nerve endings.

The surgeon controls three main parameters:

• Power (watts) — determines the intensity of energy delivery
• Spot size — controls the width of the beam and therefore the precision and power density
• Exposure mode — continuous wave, pulsed, or superpulsed, which affects the thermal spread into surrounding tissue

Superpulsed mode delivers very high peak power in extremely short pulses, minimizing thermal damage to adjacent tissue. This is particularly important for delicate procedures in the oral cavity, around the eyes, or near critical structures.

Veterinary procedures where CO2 laser excels

The CO2 laser is appropriate for almost any soft-tissue surgical procedure. The following applications are where it offers the most significant advantage over conventional scalpel or electrosurgery:

Dermatology

• Skin mass and tumor removal — reduced bleeding is especially valuable for vascular masses; the laser simultaneously cuts and coagulates
• Chronic pododermatitis — precise debridement of infected or hyperplastic interdigital tissue
• Ear canal surgery — laser ablation of chronic hyperplastic tissue in cases of end-stage otitis
• Cyst, papilloma, and skin tag removal — quick, clean procedures with minimal patient morbidity

Oral and dental surgery

• Gingivectomy and gingival hyperplasia — precise removal of overgrown gingival tissue with good hemostasis
• Oral mass excision — especially valuable for vascular oral tumors
• Feline stomatitis — laser excision of inflamed caudal oral mucosa in conjunction with dental extractions

Upper airway and ENT

• Brachycephalic obstructive airway syndrome (BOAS) — staphylectomy (soft palate reduction), stenotic nares correction, and tonsillectomy are among the most commonly cited laser procedures for brachycephalic breeds
• Everted laryngeal saccules — laser ablation as part of a comprehensive BOAS procedure

General soft-tissue surgery

• Ovariohysterectomy and castration — some practices use the laser for the skin and subcutaneous incision to reduce bleeding and postoperative discomfort
• Eyelid surgery — correction of entropion or ectropion with precise tissue control
• Perianal surgery — anal sacculectomy, perianal fistula management, and mass removal

Exotic animal applications

CO2 lasers have been used across virtually all veterinary species — including birds, reptiles, rabbits, ferrets, and small mammals. The precision and reduced bleeding are especially valuable in small exotic patients where blood loss is a proportionally greater risk.

Equipment selection: what to evaluate

Power output

Most veterinary CO2 lasers offer 10 to 40 watts of power. For general practice, 20–30 watts is sufficient for the majority of soft-tissue procedures. Higher power (30–40 watts) is useful for thicker tissue and larger patients. Lower power units (10–15 watts) may be adequate for small-exotic and dermatologic procedures but can be limiting for general surgery.

Delivery system

Two main delivery systems exist:

• Articulated arm — a mechanical arm with mirrors that directs the beam. These can be cumbersome, especially in the oral cavity, and the mirrors can become misaligned over time, requiring off-site servicing.
• Flexible fiber / hollow waveguide — a flexible tube that delivers the beam to the surgical site. More maneuverable, easier to use in confined spaces (oral cavity, ear canal), and generally preferred for veterinary applications.

Spot size and handpiece options

Interchangeable handpieces with different spot sizes and tip geometries allow the surgeon to switch between cutting, ablation, and coagulation modes. Look for a system that offers a range of tips appropriate for the procedures you plan to perform.

Safety features

Required safety features include:

• An interlock system that disables the laser when the foot pedal is released
• A visible beam aiming laser (helium-neon or diode) for targeting
• Protective eyewear specific to the CO2 wavelength (10,600 nm) for all personnel in the room
• A smoke evacuator to capture the laser plume (potential biohazard)

Service and warranty

Because veterinary medical devices are not subject to FDA pre-market review or post-market reporting requirements (see our article on veterinary medical device regulation), the manufacturer's warranty, service response time, and availability of replacement parts are critical evaluation criteria. VetScalpel, the only American-made veterinary CO2 laser manufacturer, emphasizes domestic service and support as a differentiator.

Cost considerations

A new veterinary CO2 surgical laser typically costs $10,000 to $30,000 depending on power, features, and manufacturer. Financing options are usually available. Consumables (tips, smoke evacuator filters, protective eyewear) add ongoing costs. The equipment does not typically require a dedicated surgical suite — it can be used in an existing surgery room with appropriate safety protocols — but it does require laser-safe eye protection for all personnel and a smoke evacuation system.

CO2 laser vs. electrosurgery: when to choose each

Many practices already own a radiosurgery or electrosurgery unit (Bovie, Ellman, Surgitron) and wonder whether a CO2 laser offers enough incremental benefit to justify the additional investment. Both technologies cut and coagulate tissue, but the mechanisms and tissue effects differ:

• Electrosurgery passes high-frequency alternating current through tissue, generating heat from electrical resistance. It cuts and coagulates effectively but produces a wider zone of thermal damage (typically 0.5–1.0 mm) compared to a CO2 laser.
• CO2 laser delivers photonic energy that is absorbed by water in the tissue. In superpulsed mode, the thermal damage zone can be as narrow as 0.05–0.1 mm — significantly less collateral damage.

The practical implications:

For practices that primarily perform routine spays, neuters, and simple mass removals, electrosurgery may be sufficient. The CO2 laser becomes more valuable when the case mix includes delicate oral surgery, BOAS procedures, dermatologic ablations, ear canal work, or surgery in small exotic patients where precision and minimal thermal spread are critical.

Safety requirements

CO2 lasers are Class IV laser devices — the highest hazard classification. Safety requirements include:

• Eye protection — all personnel in the room must wear wavelength-specific protective eyewear. Standard surgical loupes or safety glasses do not provide adequate protection at 10,600 nm. The patient's eyes must also be protected, typically with moistened gauze or dedicated laser eye protection.
• Fire risk — the laser can ignite flammable materials. Drapes, surgical prep solutions, and oxygen delivery equipment must be managed carefully. Alcohol-based prep solutions should be avoided or allowed to fully dry before laser use. Non-flammable draping material is recommended.
• Laser plume management — the vaporized tissue plume can contain viable cells, viruses, and other biohazards. A dedicated smoke evacuator positioned near the surgical site is standard practice.
• Training — the surgeon and all assisting staff should complete laser safety training. The American Laser Study Club (ALSC), Aesculight/VetScalpel, and several state veterinary medical associations offer continuing education programs. The 2026 VLSS conference included hands-on labs for BOAS procedures, ear canal surgery, and dermatologic applications.

The ROI case for adding CO2 laser capability

The financial case depends on your practice's case mix and pricing structure. Key factors:

Revenue opportunity

CO2 laser procedures typically command a premium over the same procedure performed with a scalpel — partly because of the equipment cost, and partly because of the documented reduction in bleeding, pain, and recovery time that clients value. Practices that market laser surgery as a differentiator often see increased surgical caseload from clients who specifically seek it out.

Cost savings

• Reduced surgical time for some procedures (less time achieving hemostasis)
• Reduced suture and bandaging material costs for some procedures
• Shorter hospitalization times for postoperative patients
• Fewer recheck visits for some conditions

Case volume threshold

At a midrange equipment cost of approximately $20,000, with a useful life of 7 to 10 years, a practice performing 2 to 3 laser procedures per week can typically recover the investment within 12 to 18 months. This aligns with AAHA's reporting that practices adding laser surgery often recover the equipment cost quickly — in one published account, within six months — and that client acceptance of the additional laser fee is high.

Training and learning curve

The CO2 laser has a moderate learning curve. Surgeons trained in traditional scalpel and electrosurgery techniques can typically achieve competency in basic laser procedures within 10 to 20 cases. More advanced procedures — BOAS correction, oral surgery in difficult anatomical locations, and exotic animal applications — benefit from mentorship or hands-on training through continuing education programs.

The American Laser Study Club's annual VLSS conference is one of the most focused training opportunities. The 2026 program included case-based lectures, hands-on surgical labs, and equipment demonstrations from multiple manufacturers.

The technology is shared with aesthetic medicine

CO2 lasers are also a core technology in human aesthetic medicine, where they are used for skin resurfacing, scar revision, and wrinkle reduction. The fundamental physics — a 10,600 nm infrared beam absorbed by tissue water — is the same. What differs is the power density, delivery mode, and clinical protocol. In aesthetic applications, the laser is used in a fractional mode to create microscopic treatment zones in the skin, stimulating collagen production while leaving surrounding tissue intact for faster healing. In veterinary applications, the laser is typically used in continuous or pulsed mode for cutting and ablation.

The shared technology platform means that advances in laser engineering — fiber delivery systems, superpulsed modes, and precision control software — tend to cross over between the two fields. For practice owners interested in the broader landscape of laser-based medical procedures, AestheticMedGuide covers aesthetic laser technology and procedure regulation including the clinical applications, regulatory requirements, and operational considerations that are relevant to any practice incorporating laser technology.

When the CO2 laser is not the right choice

A CO2 surgical laser is not a universal upgrade. Consider carefully if:

• Your practice performs fewer than 1 to 2 soft-tissue surgeries per week — the utilization may not justify the equipment cost and ongoing maintenance.
• Your surgical team is not committed to laser safety training and protocol compliance — Class IV laser safety is non-negotiable.
• You are looking for a therapeutic (non-surgical) pain management tool — that is cold-laser therapy, not surgical laser.
• Your primary surgical caseload is orthopedic — the CO2 laser is designed for soft tissue and has limited application in bone surgery.
