Development of delivery system and excitation technique for Er : YAG laser

The demands for infrared laser which shows a good water absorption have been increased continuously in the field of medical area. The purpose of this project is development of the excitation system and optical delivery for Er : YAG laser. Therefore, we are trying to optimize the excitation spectrum of flashlamp to match the absorption spectrum of laser material well. More than 500mJ of pulse energy has been obtained with an excitation diffusive chamber. We investigated several parameters of laser transmission with 7 knuckles articulated arm.
