Abstract / Full Text

A high-power 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 maximum linearly polarized output power of 250 W with a repetition rate of 10 kHz and a pulse width of 60 ns was achieved, which is even higher than the totally nonlinearly polarized output power generated without this system. The extinction ratio of the linearly polarized 1064 nm light is greater than 2500:1.
