Abstract
Nanosecond and sub-nanosecond ultrashort pulse have good applications in medical cosmetology, microstructure machining, scientific research, etc. Using stimulated Brillouin scattering(SBS) to compress the pulse width of ten nanoseconds to one nanosecond or even picosecond which is a technical way that is economical and easy to implement. This article uses a compact single-cell structure device to pass a Nd:YAG laser-pulse with 8.05ns and 145mJ through FC-40. An ultrashort pulse with 1.35ns and 94.5mJ was obtained. The pulse width after compression was measured within 4 h, and the pulse width stability was better than 5%.
