摘要
受激拉曼散射增益具有无空间烧孔特性,通过简单的腔型设计,拉曼激光器即可实现稳定单纵模运转。同时拉曼激光波长灵活,因此拉曼激光器在特殊波长单频激光领域具有重要技术优势。近年来,随着金刚石合成技术的突破,以金刚石作为增益介质的单纵模、高功率拉曼激光器获得了快速发展。文中简要介绍了拉曼激光器的单纵模运行机制;总结了单纵模金刚石拉曼激光器的研究进展;并对单纵模金刚石拉曼激光器的发展趋势进行了展望。
Stimulated Raman scattering is a mature technology that provides laser outputs with flexible wavelengths. Stable single-longitudinal-mode(SLM) Stokes is able to be achieved in a simply designed oscillator due to the nature of spatial hole burning free of Raman gain. Therefore, the Raman laser is considered as an attractive and potential method to generate SLM output with a particular wavelength. As the single-crystal diamond synthetic technology matures, high-power continuous-wave SLM diamond Raman lasers have been widely investigated for the past few years. In this review, the mechanism of Raman SLM operation in Raman oscillator and the state art of the SLM diamond Raman lasers are summarized. At last, the future investigations of continuous-wave SLM diamond Raman lasers are proposed.
