摘要

首次在1178 nm的第一-斯托克斯波长上，实现了基于腔外结构的大功率钨酸钇钾（KYW）拉曼激光器。KYW晶体由1064 nm调q Nd:YAG激光器泵浦，重复频率为9 kHz。当入射泵浦功率为29 W时，脉冲宽度为55.5 ns，最大Stokes输出功率为4.7 W，斜率效率为40.5%。本研究为利用倍频技术产生589 nm钠黄激光器提供了良好的候选材料。

High-Power 1178 nm Pulsed Raman Laser Based on KYW Crystal

A high-power potassium yttrium tungstate (KYW) Raman laser based on an extra-cavity configuration is demonstrated at the first-Stokes wavelength of 1178 nm for the first time. The KYW crystal is pumped by a 1064 nm Q-switched Nd:YAG laser with a repetition frequency of 9 kHz. With an incident pump power of 29 W, the maximum Stokes output power of 4.7 W is obtained with a pulse width of 55.5 ns, and the corresponding slope efficiency is 40.5%. This work provides a good candidate for the generation of 589 nm sodium yellow laser by frequency doubling technology.

期刊介绍： IEEE Photonics Technology Letters addresses all aspects of the IEEE Photonics Society Constitutional Field of Interest with emphasis on photonic/lightwave components and applications, laser physics and systems and laser/electro-optics technology. Examples of subject areas for the above areas of concentration are integrated optic and optoelectronic devices, high-power laser arrays (e.g. diode, CO2), free electron lasers, solid, state lasers, laser materials'' interactions and femtosecond laser techniques. The letters journal publishes engineering, applied physics and physics oriented papers. Emphasis is on rapid publication of timely manuscripts. A goal is to provide a focal point of quality engineering-oriented papers in the electro-optics field not found in other rapid-publication journals.
