✦ Synopsis

Lasing characteristics of a diode-pumped injection seeded Tm,Ho:GdVO4 laser is presented in this letter. A Qswitched output energy of as much as 2 mJ at 20 Hz with a pulse width of 170 ns was obtained. Single-frequency, nearly transform-limited operation of the laser was achieved by injection seeded. The high power and high beam quality of this laser make it well suited for use as a coherent wind lidar transmitter on a space platform. To our knowledge, this work is the first time to investigate the injection-seeded in Tm,Ho:GdVO4 to achieve Q-switched single-longitudinal-mode output laser.

We report for the first time a Nd:GdVO 4 laser operating in a continuous wave (CW) on the quasi-three-level laser at 893 nm, based on the 4 F 3/2 -4 I 9/2 transition, generally used for a 912 nm emission. The use of a pump module with 16 passes through the crystal allowed the realization of a Nd:GdV
