宽带抽运情况下乙醇、丙酮溶液中受激拉曼散射光谱的实验研究
Experimental Study on Spectrum of Stimulated Raman Scattering in Ethanol and Acetone Pumped by Broadband Chirped Pulses
摘要
研究了乙醇、丙酮两种拉曼介质在宽带抽运情况下啁啾激光脉冲的受激拉曼散射频谱特性,得到的一级Stokes光频谱宽度与抽运光基本相当,且具有较高的转换效率,从而表明了利用"展宽-受激拉曼散射-压缩"的办法获得波长近1 μm的飞秒级超短脉冲激光信号源的实验方案具有可行性.
Abstract
The spectral properties of stimulated Raman scattering in ethanol and acetone pumped by broadband chirped pulses are examined. The spectral width of the generated first order Stokes emission is comparable with that of the pump pulse, and the conversion efficiency is also considerably high. Consequently, it is possible to obtain femtosecond laser pulses of about 1 μm wavelength, by a "broadening-SRS-compression" experimental scheme.
