Optogalvanic studies with a CO2 laser
Optogalvanic signals have been observed in low pressure, RF discharges in D2O, H2CO, NH3, SO2, H2S and H2O2 using an isotopic CO2 laser. Some newly identified coincidences in D2O, H2CO, NH3, H2S and SO2 should be useful for double resonance spectroscopy, heterodyne studies and optically pumped, far...

Summary: | Optogalvanic signals have been observed in low pressure, RF discharges in D2O, H2CO, NH3, SO2, H2S and H2O2 using an isotopic CO2 laser. Some newly identified coincidences in D2O, H2CO, NH3, H2S and SO2 should be useful for double resonance spectroscopy, heterodyne studies and optically pumped, far infrared lasers. A measurement of a D2O discharge shows that the effect of laser absorption is to increase the impedance of the discharge. Studies of a RF cell with off-axis laser excitation support a V-T, acoustic wave mechanism. |
