“…The laser repetition rate of SBS pulse compression was increased to 200 Hz with a 376-ps pulse width using a generator-amplifier double-cell structure, and there was no optical breakdown in the generator cell. Our team has also conducted remarkable research on high-repetition-rate SBS pulse compression; we obtained a sub-nanosecond-pulse output with a 1000-Hz repetition rate [ 24 , 25 ] . There are two main reasons for the scarcity of studies on high-repetition-rate SBS pulse compression based on a liquid medium.…”

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.

“…Especially, based on SBS pulse compression has been demonstrated to be an effective method to convert nanosecond long pulses into picosecond short pulses due to the advantages of low cost, simple operation, and high efficiency. High-power short-pulse with peak power of ∼GW and pulse width of hundreds of picoseconds can be obtained through this technology [34,35].…”

Pulse compression based on stimulated Brillouin scattering (SBS) is a nonlinear optical approach that efficiently converts high-energy nanosecond pulses into the picosecond. Since the first observation of SBS pulse compression, different compression structures for different input and output parameters were developed to optimize the characteristics of pulse compression in the past decades. Here, a comprehensive review of the development status of SBS pulse compression schemes is provided, meanwhile, methods and trends to the optimization of SBS pulse compression are proposed.
