Abstract
There are provided a radio frequency excited slab waveguide laser and method of stabilizing the laser power and frequency using a detection circuit which uses a variation in an incident or reflecting radio frequency signal caused by an optogalvanic effect generated from the laser itself as a reference for the stabilization. The radio frequency excited slab waveguide laser having a radio frequency generator, an unstable resonator and a lock-in stabilizer further includes the detection circuit for detecting a current signal due to the optogalvanic effect generated from the unstable resonator itself to allow a signal detected by the detection circuit to be fed back to the lock-in stabilizer.
