| Abstract: | A flash-lamp pumped Nd:YAG laser emitting 1073.8 nm is demonstrated. A thin film polarizer is inserted into the cavity for generating linearly polarized lasers. With incident pump energy of 69.6 J and pulse repetition rate of 1 Hz, output pulse energy of up to 487 mJ is obtained from a 1.0 at % Nd-doped Nd:YAG rod with a size of Ø6 mm × 110 mm. And the polarization ratio is more than 1000:1 at the output pulse energy of 487 mJ. The beam quality factors in the two orthogonal directions are 24.4 ± 0.2 and 24.6 ± 0.2, respectively. |
