Abstract

A high-repetition-frequency and high-energy ZnGeP2 master oscillator power amplifier (ZGP-MOPA) system was demonstrated. The pump source was a 2097 nm Ho:YAG laser with maximum average power of about 140 W and repetition frequency of 2 kHz. Using this pump source, the ZGP-MOPA system obtained a mid-wave infrared laser with a maximum average power of 58.9 W and pulse width of 20.1 ns, corresponding to the pulse energy and peak power of 29.5 mJ and 1.5 MW. By adjusting the divergence of seed source to match the divergence of pump source, the beam quality factor M 2 of the ZGP-OPA was 3.9 × 3.7 (horizontal directions × vertical directions), the M 2 of the signal was 2.7, and the M 2 of the idler was 2.8. The corresponding maximum average power and pulse energy were 53.3 W and 26.7 mJ.

高重复频率、高能量中波红外 ZnGeP2 澳门威尼斯人官网具系统

高重复频率和高能量 ZnGeP2 主振荡器功率放大器（ZGP-MOPA）系统得到了验证。泵浦源为 2097 nm Ho:YAG 激光器，最大平均功率约为 140 W，重复频率为 2 kHz。利用该泵浦源，ZGP-MOPA 系统获得了最大平均功率为 58.9 W、脉冲宽度为 20.1 ns 的中波红外激光，对应的脉冲能量和峰值功率分别为 29.5 mJ 和 1.5 MW。通过调整种子源的发散度以匹配泵浦源的发散度，ZGP-OPA 的光束质量因子 M 2 为 3.9 × 3.7（水平方向 × 垂直方向），信号的 M 2 为 2.7，惰极的 M 2 为 2.8。相应的最大平均功率和脉冲能量分别为 53.3 W 和 26.7 mJ。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
