演示了波长为 572.5 nm 的高功率拉曼黄色激光器。高功率拉曼激光器始终受到拉曼晶体内部各种热效应的限制。根据热效应的理论分析，内部热量积累可以通过输出透过率进行微调。采用高导热率的单片金刚石晶体作为拉曼介质，实现了黄光激光器，平均输出功率为9.2 W，斜率效率为60.8%。相关成果对于推动黄光激光在医疗、激光显示、科学研究等领域的应用具有一定的影响。
A high-power Raman yellow laser with a wavelength of 572.5 nm is demonstrated. High-power Raman laser is always restricted by various thermal effects inside the Raman crystals. Based on the theoretical analyze about the thermal effects, the internal heat accumulation can be slightly adjusted by output transmittances. Yellow laser is achieved with the average output power of 9.2 W and the slope efficiency of 60.8%, used a monolithic diamond crystal, with high thermal conductivity, as the Raman medium. The corresponding results have impacts on promoting the application of yellow laser into the fields of medical treatment, laser display, and scientific investigation.
