CO2 Laser for Surgery: Principles, Applications and Selection

How a CO2 laser works

A CO2 laser generates its beam in a resonator filled with a carbon dioxide gas mixture, producing infrared light at about 10,600 nm. Soft tissue is mostly water, and water absorbs this wavelength almost completely at the surface. The energy turns tissue water to steam within a very shallow layer, so the beam cuts or ablates tissue with limited damage to the layers beneath.

Because the beam is invisible, systems add a visible aiming beam, and delivery is through an articulated arm or a hollow waveguide rather than a standard optical fibre. In surgery the beam is typically guided through a micromanipulator on a surgical microscope, or through a handpiece for freehand work. Focusing the beam gives cutting, while defocusing gives coagulation or surface ablation.

Applications of CO2 lasers across specialties

CO2 lasers have been used for decades in many disciplines. They are common in otolaryngology and laryngeal microsurgery, oral and maxillofacial surgery, gynaecology, dermatology and plastic surgery, and in selected neurosurgical and general surgical procedures. The attraction is precision, a relatively bloodless field in small vessels and a clean ablation margin. Which tool suits a procedure is for the surgeon to decide; see laryngeal laser surgery and the ENT laser guide for specialty detail.

For a comparison with other sources, read diode versus CO2 laser. A diode or blue laser is fibre-delivered and portable, while a CO2 laser offers a line-of-sight cut with a very small spot.

The A.R.C. Laser C-Las as an example of a surgical CO2 system

The C-Las is a CO₂ laser for very fine, almost bloodless cutting and ablation of tissue, in clinical use for decades across many disciplines. It provides 30 W, or 10 W in Super Pulse mode, at 10,600 nm, with pulse lengths from 20 to 500 ms or continuous wave. Its compact design lets the laser and accessories fit on a dedicated trolley: micromanipulator, focusing handpieces, safety goggles and smoke evacuation.

The C-Pro micromanipulator delivers a 100 µm spot, adapts to all common surgical microscopes and offers a continuously adjustable working distance of 200 to 500 mm, with a focus/defocus lever to switch between cutting and coagulation. The laser measures 490 × 480 × 200 mm and weighs 32 kg, with a colour touchscreen and an air-cooled horizontal ceramic resonator. The CO2 DUO3 Concept extends the C-Las with a second laser for fibre-guided work, CORAL Blue at 445 nm or CORAL Green at 514 nm.

Safety, smoke evacuation and room requirements

CO2 lasers are Class 4. The operating room needs warning signs, eyewear rated for 10.6 µm, wet drapes near the field and a controlled access plan. Airway surgery adds the risk of fire; see laser airway fire prevention. The plume must be evacuated at source, as described in surgical laser plume evacuation.

Our medical laser safety guide covers the programme side, including who is responsible. Confirm facility requirements with DHA, DOH or MOHAP.

What to look for when buying, and supply in the UAE

Compare output power and modes, spot size and the quality of the micromanipulator, the compatibility with your microscopes, ease of focusing, scanner or handpiece options, the user interface, smoke evacuation, and the service and training available locally. Ask for a demonstration in your OR.
