Abstract
LASER is the acronym for Light Amplification by Stimulated Emission of Radiation. Increasing knowledge and availability has made it more practical for veterinary surgeons to own and operate surgical lasers. With a full understanding of laser physics and safety and following the basic preparations discussed below, veterinary surgeons can quickly master surgical lasers and make use of them in a variety of procedures. This chapter considers the following: Physics of laser light; Laser types; Safety considerations; and Applications of the CO2 laser.

High-filtration particulate surgical masks have a pore size of <1 µm. This small diameter protects the surgeon and assistant from inhaling heavy plume material. © 2012 British Small Animal Veterinary Association

A skin incision made with a CO2 laser should be clean, dry and less painful than a scalpel incision. The superpulse temporal pattern is an ideal setting for skin incisions and, if available, can be pulsed for a greater reduction in char formation. © 2012 British Small Animal Veterinary Association

Generally, the soft palate should not extend beyond the level of the caudal pole of the tonsil. The goal for laser-assisted staphylectomy is for the new soft palate to conform to the shape of the epiglottis and just barely make contact with it. © 2012 British Small Animal Veterinary Association
