We have recently made significant advances in development of all-solid-state intracavity Raman lasers generating multiwatt average powers in the near infrared and (by frequency doubling) visible spectrum, with important applications in biomedicine and remote sensing. A new generation of Raman crystals, especially tungstates, offer superior optical, mechanical and thermal properties, promising high Raman gains and choice of Stokes frequency shift. The project will investigate a range of key issues for these materials including control of the Stokes wavelength, associated polarisation control, and pump-resonator configurations giving maximum Raman laser power and efficiency. The project will lead to state-of-the-art source technology with outstanding prospects for commercialisation and practical application.

我们最近在全固态腔内拉曼激光器的发展取得了重大进展，产生数瓦的平均功率在近红外和（倍频）可见光谱，在生物医学和遥感的重要应用。新一代的拉曼晶体，特别是钨酸盐，提供了上级的光学，机械和热性能，有前途的高拉曼增益和斯托克斯频移的选择。该项目将研究这些材料的一系列关键问题，包括斯托克斯波长的控制，相关的偏振控制，以及提供最大拉曼激光功率和效率的泵浦谐振腔配置。该项目将带来最先进的源技术，具有商业化和实际应用的突出前景。
