Continuous Optically Pumped Cs Laser

Abstract

A continuously operating 7.18-μ laser oscillator has been built using optically pumped cesium vapor as the amplifying medium. A power of 50 μw is coupled out of the confocal resonator by means of a 45° BaF2 pickoff window. The measured intensity distribution is in good agreement with that derived from the Boyd-Gordon expression for the lowest-order mode.
