Abstract

Abstract:

In this paper, based on Nd:YAG/V:YAG bonded crystal, the output characteristics of an passively Q-switched microchip laser operating at 1 338 nm was demonstrated under cw and quasicw LD endpumping. In the cw pumping region, stable Q-switched pulse was obtained with the maximum output power of 0.73 W and a pulse width of 139 ns. Under the quasicw pumping region, the phenomenon of passive modelock Q-switched was achieved, the maximum output power was 1.01 W and the pulse width was about 80 ns. Among them there was modelocked pulse train in the Q-switched pulse with single pulse width of 70 ps. The experiment results show that Nd:YAG/V:YAG bonded crystal have the advantages in obtaining 1 338 nm compact pulse laser with high output power and quasicw pumping mode can greatly decrease the thermal effects and ensure high laser output power.
