Power stabilization of radio frequency excited slab laser using optogalvanic effect

摘要

We stabilized an optical power of RF excited slab CO_2 laser on the pick of the Doppler broadened gain curves using an optogalvanic effect generated from the laser itself. The power stability is greatly improved to 2.9percent. We suggest that this method can be applied for frequency and power stabilization of other kinds of RF excited laser, for example, Xe and CO laser.
