Continuous-wave laser characteristics of a Nd~(3+):LaB_(3)O_(6) cleavage microchip and the influence of thermal effects

摘要

With pumping by a Ti:sapphire laser, the cw laser characteristic of a 5.6 at. percent, 0.5 mm thick Nd~(3+):LaB_(3)O_(6) cleavage microchip in an end-pumped plano-plano resonator is researched. A slope efficiency of up to 49percent and a maximum output power of 530 mW are obtained at an absorbed pump power of 1.16 W and an optimal output coupler transmission of 3.2percent. Choppers with different duty cycles are used to change the thermal effects in the microchip, and the influences of thermal effects on the laser characteristics of the Nd~(3+):LaB_(3)O_(6) cleavage microchip are investigated.
