Thermal lensing effect controling system for medical laser

摘要

The present invention relates to a medical laser thermal lensing effect control system, which uses a mechanical switch to stably and uniformly control a thermal lensing effect despite a change in the frequency of a laser output. It's about the system. The medical laser thermal lens effect control system of the present invention comprises: a laser driving unit including a power supply unit and a microprocessor unit; a seed laser unit oscillating and emitting a low-power laser light by generating a seed light having a narrow line width having a constant overlapping frequency according to a driving signal of the laser driver; a first optical path unit for primary amplification of the laser light input from the seed laser unit; It is composed of a second optical path unit for secondary amplifying and outputting the laser light amplified by the first optical path unit, and the first optical path unit is provided with a mechanical switch that selectively blocks or allows the laser light to be incident. There are technical features.
