Abstract

Doppler-free optogalvanic spectra of two neon lines have been observed, with a radiofrequency oscillator used to both excite the discharge and detect the laser-induced change in ion density. Both intermodulated and polarization-intermodulated (POLINEX) methods have been used. The sensitivity is similar to that obtained with fluorescence detection.

Isotope shift of 667.7 nm transition in atomic argon
1986, Physics Letters B
Doppler-free optogalvanic measurements of the 667.7 nm $4 s [32]_{1}$ to $4 p [12]_{0}$ transition in ^36,38,40Ar have yielded values for the isotope shifts, field shifts and δ〈r²〉. The field shift, calibrated with muonic X-ray data, confirm a significantly larger δ〈r²〉 for ³⁸⁻⁴⁰Ar (0.17 fm²) than for ³⁶⁻³⁸Ar (0.07 fm²) consistent with similar data for K and Ca crossing the $1 f_{72}$ magic neutron number N = 20.
Optogalvanic studies with a CO laser
1986, Optics Communications
Optogalvanic signals are reported in low pressure, RF discharges in NO, NO₂, H₂O, HNO₃, HCO₂H, H₂CO and C₂H₂O₂, using an infrared, isotopic CO laser. The results illustrate the role of the OG technique in locating coincidences useful for other spectroscopic investigations and perhaps for optically pumped, far infrared lasers. The formation and simultaneous OG detection of the free radical NO, when using NO₂, is also reported and quantified.

Stable-isotope ratio analysis based on atomic hyperfine structure and optogalvanic spectroscopy
1984, Talanta
Atomic hyperfine structures were measured for the Cu I transition at 5782 Å by optogalvanic spectroscopy at high resolution, with a cw dye laser. Samples were electro-deposited on the demountable cathode of a home-made hollow-cathode lamp. By spectral deconvolution, the relative isotopic abundances of ⁶³Cu and ⁶⁵Cu could be determined with good accuracy and precision. The technique is applicable to copper concentrations as low as 1.6 ppm.
