MORRIS MOSSERI, MD Boston, Sfarscrl .''t Tn , lathe short span of one decade . cardiovascular applications of laser technology have progressed from a laboratory curiosity to a device for coronary revascularization approved by the Food and Drug Administration . It is no coincidence that this same decade witnessed the full maturation of pulsed laser technology . Development of laser technology . Initial biomedical applications of laser technology relied nearly exclusively on continuous wave lasers. The output power achieved by these lasers was typically well under 100 W . The continuous fashion in which continuous wave laser irradiation was administered consistently overwhelmed the ability of boundary tissues to dissipate heat responsible for target tissue ablation . Even frequent interruption of the laser output (so-called chopped mode) proved inadequate to prevent thermal injury (1) . as compensatory mechanisms designed to achieve a similar magnitude of tissue ablation were limited to simply increasing cumulative exposure time. Although the ultimate sequetae associated with thermally injured tissue continue to be debated, there is no debate regarding the extent to which medium-sized arteries failed to tolerate the potent vasoconstrictor effects of heat generated by these lasers (2) . The latter ultimately made continuous wave lasers unsuitable for use in coronary arteries . The twin insults of thermal injury and vasospasm were successfully addressed by the advent of the pulsed laser. The design of this second-generation laser permitted sufficient storage of energy before each discharge so that instead of watts, these lasers delivered peak powers in the megawatt or kilowatt range .
