Diode-Pumped Tm:YAP Laser for Eye Microsurgery

摘要

Pulsed tunable diode-pumped Tm:YAP laser was characterized and used for preliminary investigation in eye microsurgery. By means of Lyot filter, the laser emission was tuned between a high (120 cm~(-1) @ 1940 nm) and two times lower (50 cm~(-1) @ 2040 nm) value of radiation absorption in water. In the interaction experiment, the eye tissue (in vitro) was irradiated with tunable Tm:YAP laser radiation, and the effects of cutting and coagulation depth in wavelength range from 1940 nm up to 2040 nm were investigated. The results were documented by optical microscope.
