Actively Q-switched laser performance of Nd:LuAG crystal with birefringence compensator

摘要: A laser diodes dual-end-pumped 1064 nm pulsed based on two Nd:LuAG crystal slabs using a quarter-wave plate to reduce depolarization loss is reported. The experimental results showed that both the degree of polarization and conversion efficiency increased. electro-optic Q-switched operation was realized at repetition rate 500 Hz with single pulse energy 13 mJ output. Its slope optical-to-optical were 24 20 % respectively. shortest width 9 ns recorded, corresponding an output peak power as high 1.4 MW for each pulse. beam quality factors \( {\text{M}}_{\text{x}}^{2} = 1.7 \) {\text{M}}_{\text{y}}^{2} 1.85 \).
