Abstract

We report on single and dual-wavelength laser performance of a diode-side-pumped neodymium-doped YAG crystal in the range of 1.3–1.44 µm with switchable spectral output due to an intracavity Pellin–Broca prism for the first time, to the best of our knowledge. Polarized laser pulses with an energy of 402 mJ at a wavelength of 1338 nm were obtained under an optical pumping energy of 3.6 J. Oscillations of six spectral components at wavelengths of 1319, 1338, 1356, 1415, 1432, and 1444 nm with a slope efficiency of 19.1, 20.1, 19.7, 4.65, 4.82, and 8.19%, respectively, were obtained. The dual-wavelength oscillations at 1319 + 1338, 1338 + 1356, 1415 + 1432, and 1432 + 1444 nm were obtained for an intermediate position of the output coupler with a slope efficiency of 17.6, 21.7, 2.65 and 6.3%, correspondingly. Our results showed that the Nd:YAG laser with an intracavity Pellin–Broca prism is promising for producing high-energy laser pulses with single and dual-wavelength output in the spectral range of 1.3–1.44 µm.

工作波长范围为 1.3-1.44 µm 的二极管侧泵浦脉冲 Nd:YAG 激光器，提供单波长和双波长输出

据我们所知，我们首次报道了二极管侧泵浦掺钕 YAG 晶体在 1.3-1.44 µm 波长范围内的单波长和双波长激光性能，该晶体通过腔内佩林-布罗卡棱镜实现了可切换的光谱输出。在 3.6 J 的光泵浦能量作用下，获得了波长为 1338 nm、能量为 402 mJ 的偏振激光脉冲。在波长为 1319、1338、1356、1415、1432 和 1444 nm 处，获得了六个光谱分量的振荡，斜率效率分别为 19.1、20.1、19.7、4.65、4.82 和 8.19%。在输出耦合器的中间位置，1319 + 1338、1338 + 1356、1415 + 1432 和 1432 + 1444 nm 波长处出现了双波长振荡，斜率效率分别为 17.6%、21.7%、2.65% 和 6.3%。我们的研究结果表明，带有腔内佩林-布罗卡棱镜的 Nd:YAG 激光器有望在 1.3-1.44 µm 光谱范围内产生具有单波长和双波长输出的高能激光脉冲。
