Abstract
The power supply includes an oscillator (20) which generates a radio-frequency signal amplified by an amplifier (21). The amplified signal is applied to a laser (22) to initiate and maintain a discharge in the laser gaseous active medium. Power control means (24) are provided operable after initiation of the discharge to adjust the power applied to the laser to the value required to operate the laser at maximum efficiency. Automatic gain control means (25) may be provided, responding to the output from a power meter (23).
