High-peak-power, short-pulse-width, LD end-pumped, passively Q-switched Nd:YAG 946 nm laser

摘要

High-peak-power, short-pulse-width diode pumped 946 nm Nd:YAG laser in passively Q-switching operation with Cr~(4+):YAG is reported. The highest average output power reaches 3.4 W using the Cr~(4+):YAG with initial transmissivity T_0 = 95%. When the T_0 = 90% Cr~(4+):YAG is employed, the maximum peak power of 31.4 kW with a pulse width of 8.3 ns at 946 nm is generated.
