Level-crossing Optogalvanic Spectroscopy

Applications of Optogalvanic Effects in Opening Switches

Optogalvanic effects are changes in the electrical properties of a gas discharge caused by illumination with radiation at a wavelength corresponding to an atomic or molecular transition. The resurgence of interest in optogalvanic effects stems in a large measure from the unique properties of lasers such as: the high powers, the tunability, the narrow bandwidths, and the controllability of pulse...

Experimental and Theoretical Studies of Optogalvanic Effects in Neon Discharges

TWO PHOTON TRANSITIONS IN THE OPTOGALVANIC SPECTRUM OF NEON

Seventeen two-photon transitions for neon have been observed in the 580- 635 nm spectral region for use in the spectroscopic study of its higher excited levels, which are not accessible by one-photon absorption. To compare the two and one-photon absorption signals originating from the same lower level, an effort was made to record single-photon optogalvanic spectrum in the available wavele...

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.
