Abstract

The short duration repeat pulse laser has advantage prevent of carbonize and sharp cut for biotissue. We considered the medical applications of higher power pulse CO2laser. We have investigated IR beam guide by hollow tube for COlaser. The hollow tube with compound the metal and polymer is effectively system for CW CO2 higher power laser beam transmission. We have tried to transmit the high peak power pulse C02 laser beam with hollow tube guide. Using the C02 laser have high peak power(22MW max.),short pulse duration(8Ons) and repeat pulse(under lOpps). In this experiments, the laser beam transmittance was obtained ca.90% per meter in straight state hollow tube. The delivery peak power was 1.5MW,energy per pulse was l2OmJ and average power was 1.2W.
