• The Laser system consists of power supply unit 6KW9709-35, cooling unit HEX9604, control unit CU21-70, housed in a 19-inch cabinet, and a laser head.
• The Quasi-CW Q-Switched Nd:YAG Laser PR21-70 can be run in two modes:
    a) with manual control from the front panel of the power supply unit;
    b) with PC-control via Interface RS-232.
• The Quasi-CW Q-Switched Nd:YAG Laser PR21-70 is equipped with a microprocessor controller to provide its timing with an external device and other lasers both in mode SYNCHRO IN and in mode SYNCHRO OUT.
• In the PC-control mode, the operator can enable or disable the intracavity shutter (ON/OFF), start up or shut down the laser, control the pulse repetition rate or the arc-lamp operational current.
• The Quasi-CW Q-Switched Nd:YAG Laser PR21-70 is equipped with all necessary safety and functional interlocks. They allow shut down of the power supply at cooling liquid over-temperature, when the amount or flow rate of the cooler is not sufficient, or when the laser head covers are removed.
• The dedicated Software controling the laser operation contains a specific diagnostics window to permit control of the main parameters of the laser system in operation.
