Observations of stimulated emission from high-pressure krypton and argon/xenon mixtures

Abstract

Experimental data demonstrating coherent oscillation in high-pressure krypton at 1457 ± 1 Å with an 8-Å linewidth are reported. Observations of stimulated emission from argon/xenon mixtures arising from the operation of efficient energy transfer processes and resulting in a twofold enhancement of the xenon laser output at ∼ 1720 Å are also given. The influence of collisional-induced absorption on the oscillator output is indicated by the measurement of a blue shift in the spectrum of the stimulated output for argon/xenon mixtures relative to the case of pure xenon.
