Output characteristics of high-power stimulated Brillouin scattering pulse compression enhanced by thermal effects based on HT270
文献摘要：
Thermal effects are typically considered as obstacles to high-repetition-rate stimulated Brillouin scattering(SBS)pulse compression.In this paper,a novel method is proposed for improving the SBS output characteristics by exploiting thermal effects on the liquid medium.Using HT270,the SBS output parameters with the medium purification and rotating off-centered lens methods are studied at different repetition rates.The results indicate that these two methods can alleviate thermal effects and improve the energy efficiency,but the rotating method reduces the energy stability because of the aggravated optical breakdown at the kilohertz-level repetition rate.For a 35-mJ pump energy,the energy efficiency at 2 kHz without the rotating method is 30％higher than that at 100 Hz and 70％higher than that at 500 Hz.The enhancement of the SBS output characteristics by thermal effects is demonstrated theoretically and experimentally,and 2-kHz high-power SBS pulse compression is achieved with HT270.
