High polarization degree, high-power Q-switched 1064 nm output with efficient depolarization compensation
A high power of linearly polarized 1064 nm light with high polarization degree was achieved by using a compact straight cavity. We carefully designed the Q-switched diode-side-pumped Nd:YAG laser cavity with two laser modules. By using a linearly polarized generation and compensation system, the highest linearly polarized output power obtained was 250 W with a repetition rate of 10 kHz and pulse width of 60 ns, which is even higher than the totally non-linearly polarized output power generated without this system. The extinction ratio of the linearly polarized 1064 nm light is greater than 2500:1.
