Output voltage detecting device in a laser oscillator.

摘要

An output voltage detecting device is disclosed for a laser oscillator in which laser oscillation is performed by applying a high frequency voltage to a laser tube (14). The device comprises a transformer coil (15) connected to an output of an high frequency power supply unit (11) which supplies the high frequency voltage. A current flowing in the coil (15) is detected to monitor the output voltage. <IMAGE>
