Abstract

Abstract: The continuous wave and passively Q-switched output performance of 808 nm laser diode array side pumped Nd∶YAG ceramic and Nd∶YAG single crystal are studied. In the condition of 145 W pump power and 20% output coupler transmission of a plano-plano resonator, the Nd∶YAG ceramic obtains a continuous wave output power of 44.28 W at 1 064 nm, the optical-to-optical conversion efficiency is 30.5%, the slope efficiency is 38.2%. In the same experimental condition, using Cr⁴⁺∶YAG as the passive Q-switcher, the 10.03 kHz quasi-continuous laser is obtained when the original transmission ratio is 87.89%, the average power is 4.62 W and the peak power is 5.54 kW. Compared to the same size and doping concentration of Nd∶YAG single crystal in the same experimental condition, the result shows that Nd∶YAG ceramic laser has a widely application in high power.
