Abstract
A Cr:LiSrAlF6 (Cr:LiSAF) laser has been diode pumped. Both cw and long pulse diode pumping were demonstrated with pump power levels as high as 300 mW cw and 1 W pulsed. Polarization combination of pump diodes to reach threshold was demonstrated with two low power lasers. The maximum output power obtained was 26.5 mW cw and 175.8 mW pulsed. Analysis of the data show the passive loss level of the crystal is less than 0.1% cm−1. Details of the Cr:LiSAF crystal growth and high power diode architecture are presented, along with optical characterization data for the laser resonator.
