Abstract

We report an experimental study of SRS of chirped 40-ps Ti : sapphire laser pulses with a transform-limited duration of 0.35 ps and centre wavelength of 925 nm in BaWO4 crystals. The highest generation efficiency for the ∼925 cm−1 shifted Stokes signal of SRS by the ν 1 vibrational mode of BaWO4 crystals has been reached using three sequentially located crystals with a total length of 3.3 cm. The position of the crystals after a focusing mirror has been optimised, which has ensured a pump-to-Stokes conversion efficiency of ∼50 % in terms of spectral brightness and ∼20 % in terms of pulse energy.

啁啾Ti:蓝宝石激光脉冲在BaWO4晶体中的高效SRS

本文报道了在BaWO4晶体中啁啾40-ps、变换限制持续时间为0.35 ps、中心波长为925 nm的Ti:蓝宝石激光脉冲的SRS实验研究。利用3个总长度为3.3 cm的BaWO4晶体的ν 1振动模式产生SRS的~ 925 cm−1位移Stokes信号的效率最高。晶体在聚焦镜后的位置得到了优化，这确保了在光谱亮度方面的泵到斯托克斯转换效率为~ 50%，在脉冲能量方面为~ 20%。
