“…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.

In this work we demonstrate the compression of laser pulses at a high repetition rate, using transient stimulated Brillouin scattering (SBS). Output pulses with pulse durations close to the quarter-acoustic wave oscillation period (τf) was obtained. We find that the primary factors which limit the compression of pulses under high repetition-rate, transient conditions are the inherently low gain in the transient regime, thermal accumulation within the SBS medium and optical breakdown. We show that short phonon lifetimes can suppress the trailing edge amplification of the output pulse, while also reducing the threshold and improve energy efficiency. In this work, we demonstrate the generation of output laser pulses with a repetition-rate of 200 Hz and an average pulse duration of 1.08τf using the electronic-fluorinated liquid FC-43. Due to the fast decay of the acoustic field, compressed pulses with duration <τf were also observed. We also demonstrate efficient output of pulses with repetition-rate of 200 Hz and energy efficiency of up to 40% using the heat transfer fluid HT-230.
