Paper Abstract

The high-resolution absolute-intensity spectrum of a Vortek-arc lamp is obtained in order to evaluate the lamp as a candidate for a pump source for crystal-laser amplifiers. Spectra are also obtained at lower resolution for Ar-Kr and Ar-Xe mixtures. These spectra are convolved with the Nd:YAG absorption cross section assuming YAG crystal thickness of 0.5 cm and doping of 2 x 10 to the 20th/cu cm. Emphasis is placed on wavelength and intensity calibrations, assembling the spectral regions, and low-resolution spectra. A spectral overlap with Nd:YAG bands is discussed, as well as pulsed operation, lamp-tube filtering, and electrical efficiency. It is noted that pulsing of the lamp should be possible and may provide further improvements in laser operation.
