✦ Synopsis

The different upconversion dynamic processes in Tm,Ho:GdVO4 crystal pumped by 100 fs pulse laser and continue-wave diode laser at 800 nm are analyzed. A phononhelped absorption theory is used to explain the different upconversion processes in Tm,Ho:YLF and Tm,Ho:GdVO4. In addition, the lifetime 16 µs of Ho: 5 S2 level in GdVO4 is firstly measured.

A room-temperature diode-end-pumped acoustooptical (AO) Q-switched Tm:GdVO4 laser was firstly reported. The minimum AO Q-switch pulse width was measured to be about 48 ns with output power of 2 W and repetition rate of 5 kHz. Continuous-wave output power of 2.8 W at 1912 nm was obtained under the ab
