Paper Abstract

The laser coagulator is assigned to the coagulation of an eye retina. It has been built on the basis of semiconductor cw laser, SDL-2482 P1 type. The laser is integrated with the monitoring photodiode, thermistor, and thermoelectric cooler. The electronic system ensures a continuous work (cw) and pulse work of the coagulative laser. For the continuous work, the time of laser operation depends on how long the operator presses a pedal. Exposure duration is displayed at the time-meter. The pulse operation enables previous setting of pulse duration. Time of laser switch on can be regulated from 0 to 5 s with the resolution of 0.1 s. The output laser power is regulated continuously from 1 mW to 3 W and it is displayed at the power meter display. The laser controller is equipped in the series of systems protected against the exceeding of permissible work conditions.
