Paper Abstract

The authors describe room temperature, flash-pumped laser operation of several Cr3+-sensitized, Tm3+-activated garnet crystal hosts. The hosts which have been investigated include YAG, YSGG, and GSGG. Laser action for these systems is based on the 2.0 micrometers, 3F4yields3H6 transition in Tm3+. Slope efficiencies for the 2 micrometers transition exceeded 4% in some of the hosts investigated. Free-running, multimode output energies have exceeded 2 J at 1 Hz repetition rates, while TEM00 output energies of greater than 1 J have also been reported.
