0.85 Micron Solid State Laser Material Evaluation. Part 2

Abstract

This second semi-annual report describes the current status of the program for the development of a room temperature, 0.85 micron optically pumped laser material, er: YLF. Substantial progress has been made in defining the physical, spectroscopic and laser characteristics of this material. The measured value of the stimulated emission cross section is 1.5 x 10 to the -19th power sq cm. Laser oscillations in this material are predominantly pi polarized. Long pulse operation at up to 33 pps is reported. The maximum observed output power was of 0.25 watts at 11 pps from a 5.5 x 52 mm 2% Er rod.
