Use of the optogalvanic effect and the uranium atlas for wavelength calibration of pulsed lasers.
The optogalvanic effect in a commercial uranium hollow cathode discharge can be used in conjunction with the uranium atlas for wavelength calibration of pulsed lasers at wavelengths longer than 3500 A. At shorter wavelengths photoelectric emission from the cathode surface interferes with the measurements. The use of a tubular hollow cathode eliminates interference from photoelectric emission and permits wavelength calibration at shorter wavelengths. The photoelectric emission is measured as a function of wavelength.
