铯蒸汽中受激电子喇曼散射
Stimulated electronic Raman scattering in Cs vapour and picosecond pulses generation in infrared region
摘要
本文报导了利用微微秒脉冲系列在铯原子蒸汽中产生受激电子喇曼散射,得到强微微秒红外脉冲的实验结果.波长为527nm的绿光经喇曼频移产生2.28μm的红外输出,最大能量达1mJ,量子转换效率为16%.实验测量了红外辐射强度及受激电子喇曼散射的阈值对蒸汽压、泵浦光强度的依赖关系,并进行了分析和讨论.
Abstract
The generation of high-power picosecond IR pulses by stimulated electronic Raman scattering (SERS) using ps pulse trains is reported. 20 pa pulses at 527 nm have been Ramanshifted to produce 1 mJ maximum pulses at 2.28μm with 16% quantum efficiency. IR output energy and the threshold of SERS as a function of the pumping energy and vapour pressure are measured and analysed.
