CO(2) laser frequency stabilization using the radio-frequency optogalvanic Lamb dip.
The Lamb dip of the CO(2) saturation signal in an extracavity low-pressure CO(2)-N(2) rf glow discharge is detected optogalvanically and used to stabilize the frequency of a CO(2) laser. The frequency stability is estimated to be better than 100 kHz.
