Semiconductor laser tubes are very sensitive to temperature and can easily cause thermal damage

According to the environmental requirements of medical electrical equipment, the semiconductor laser treatment instrument must select a climate and environment group, that is, the semiconductor laser treatment instrument must meet a specified operating temperature range, and the laser power generated by the semiconductor laser tube is very sensitive to temperature changes. It can be seen from the curve that as the working temperature rises, the laser power will drop rapidly. However, as a medical laser, in order to ensure the clinical effect of laser treatment, it is necessary to ensure the accuracy of the irradiation dose of laser treatment, and it is necessary to increase the work rate through the feedback control circuit. Current, keep the laser power relatively stable, wh
