Solid-state radio frequency oscillator for optogalvanic spectroscopy - Detection of nitric oxide using the 2-0 overtone transition
A compact, solid-state radio-frequency oscillator of low-power consumption is described, which allows quantitative measurement of the optogalvanic effect in low-pressure gas discharges. The oscillator has been used to record a portion of the 2-0 overtone band of nitric oxide at a pressure of about 1 Torr using a tunable color-center laser operating at 2.65 microns.
