    摘要: 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.

    摘要: An apparatus for and a method of stabilizing the laser power and frequency of a radio frequency excited laser, which are adapted to lock the laser power and frequency of the laser at the vertex of a laser gain curve using an optogalvanic effect generated from the laser itself, thereby stabilizing the laser power and frequency without requiring any specific unit to be arranged inside or outside a cavity of the laser. A capacitor is coupled to a radio frequency inlet of the radio frequency discharge tube. The capacitor serves to induce a part of radio frequency energy, introduced into the radio frequency discharge tube, toward a detector, so that the optogalvanic signal is measured, based on the induced signal, after removing radio frequency components from the induced signal by the detector, thereby enabling a measurement of a variation in input radio frequency energy caused by the optogalvanic effect. Accordingly, it is possible to provide a stable, simple and compact laser exhibiting an improved laser efficiency.
