Intracavity-pumped 2.09-µm Ho:YAG laser
Abstract
The 2.09-micron Ho:YAG 5I7-5I8 laser transition is intracavity pumped by a Tm:YAG laser. Separate Tm:YAG and Ho:YAG crystals share a single laser cavity, the Tm:YAG crystal is pumped at 785 nm, and the resulting 2.01-micron Tm(3+) laser emission pumps the Ho:YAG crystal. The slope efficiency of the 2.09-micron Ho(3+) laser output is 42 percent of the absorbed 795-nm pump power.
