Abstract

The thermal focal length of a Tm,Ho:GdVO4 crystal was measured in this paper. The pump laser was 25.73 W, and the thermal focal length was 692.6 mm; based on the thermal focal length of a Tm,Ho:GdVO4 crystal, a single end-pump continuous wave (CW) operation of Tm,Ho:GdVO4 laser was designed to demonstrate the effect of thermal focal length, and a 0.26-W output power was high in considering the thermal focal length than in unconsidering the thermal focal length with a 26.1-W pump power.
