Abstract

An electrically self-oscillating radio frequency-excited gas laser. The discharge section of the laser resonates at a desired radio frequency as a result of incorporating the discharge section into the feedback loop of a power oscillator circuit. This laser structure facilitates initial plasma breakdown and adapts its frequency depending upon whether the gas in the discharge section has broken down. When the laser plasma tube is integrated with the oscillator, the laser is also somewhat smaller compared to gas lasers having conventional crystal-controlled amplifier chains.
