Mirror vs. the Lens: What's Best for the Laser Surgery?

摘要

Many surgical procedures today are performed with lasers. Most medical laser companies produce a variety of lasers units, such as CO2, Nd:YAG, Erbium, Excimer, Argon, and others. Each radiates a unique wavelength of light for use in a range of surgical procedures. Many of these wavelengths lie outside the visible spectrum. To allow surgeons to target the invisible beam, medical lasers transmit a secondary, low-power, visible aiming beam coincident with the high-power treatment beam. The laser delivery system's most important characteristic is the precision with which the size and location of the aiming beam coincide with the size and location of the treatment beam at the surgical site.
