A comparison of the laser performance of the 5I7 >>5I8 transition at 2.1 micron in multiply doped Ho :YLF and Ho :YAG both in CW and pulsed operating modes is reported. CW operation was carried out at liquid nitrogen temperature, while the pulsed laser was operated in the temperature range from 86K to 220K. In bath YAG and YLF, the laser threshold shows a fast rise with temperature. The total laser power at high pumpimg levels gradually decreases with temperature in YAG. In YLF, however, the laser output is peaked around 150K. The laser performance as a function of temperature, pumping energy and coupling mirror will be presented.
