Abstract
Good signal-to-noise ratio optogalvanic effect has been obtained in two kinds of hollow cathode discharges (coil and segmented construction) using commercially available low cost and low power diode lasers emitting in the visible region of the spectrum. The OG profiles of Ne and He transitions, suitable for diode laser wavelength locking to absolute reference, have been studied. The amplitude and sign of the optogalvanic signal have been measured simultaneously with the absorption in dependence of the gas discharge parameters in order to find the conditions for optimum OGS. OGS was observed also at a wavelength of 667.28 nm, where no transition was found in the tables of spectral lines available.
