在450 ps钛宝石（Ti:Sapphire） 激光激发下, 获得了C3H6O的受激拉曼散射（SRS），以钕玻璃为荧光增强介质，放大了1.053 μm的Stokes 辐射，能量转换效率达到17.5％, 一阶斯托克斯波带宽为25 nm，脉冲宽度为318 ps。讨论了皮秒脉冲激发的受激拉曼散射效应及荧光增强SRS机理及其潜在应用。

A high efficient conversion from the Ti: Sapphire laser to the Raman laser with 1053 nm wavelength at the area of picosecond (ps) pulse duration is reported. A Ti:Sapphire laser (808 nm wavelength,450 ps pulse duration and 10 mJ pump energy) is employed as the pump source, acetone is stimulated to generate first-order Stokes wave with 1053 nm central wavelength. Inserting Ndglass as a fluorescence enhancement medium, the first-order Stokes wave is obviously enhanced, the energy conversion efficiency from pump laser to the first-order Stokes wave reaches to 17.5％, the bandwidth of the first-order Stokes is 25 nm, and the pulse duration is 318 ps. The physical mechanism together with the potential applications are discussed.
