Eyesafe Rare Earth Crystal Lasers for Atmosphere Soundings

Abstract

The characteristics of room temperature Er(3+):YAG lasers at 1.644 microns end pumped by an Er(3+):glass laser at 1.535 microns described. Low threshold and efficient operation was obtained for 0.5 and 1% Er(3+):YAG. Similar studies were performed utilizing 0.7% Er(3+) (3% Yb(3+), 1% Cr( 3+)YSGG. Laser action of Er (3+):YSGG at 1.643 microns was achieved for the first time. Solid state lasers, Er(3+):YAG:1.64 microns, Er(3+):YSGG:1.64 microns.
