Abstract

A room-temperature Tm,Ho:YLF laser is constructed with a 2.5-mm-long Tm(6%) and Ho(0.4%) co-doped yttrium lithium fluoride crystal pumped by a laser diode operating at 792nm. The output power as a function incident pump power at different output coupler transmission values is given. At room temperature, the laser operates on a single transverse mode (TEM₀₀) at 2.066μm, the laser threshold pump power is 55mW, and its maximum output power and optical-to-optical conversion efficiency are 388mW and 14.1% respectively. At the same time, the output power and optical-to-optical conversion efficiency as a function of incident pump power at different temperatures are obtained. Furthermore, the experimental results are explained reasonably.
