High stability hundreds of picoseconds pulse compression using self-pumped SBS
Abstract
A new method of self-pumped stimulated Brillouin scattering (SBS) pulse compression utilizing feedback from the rear window of an SBS-medium cell is presented. In this work, the experimental system utilizes HT-230 to compress a 9.5 ns laser pulse to one with pulse duration of 360 ps. The RMS of pulse duration of the self-pumped SBS output is 6.3%, which is nearly 2.5 times lower than that of the noise-excited SBS. This work demonstrates a simple and practical approach to using self-pumped SBS process for obtaining the stable hundreds of picoseconds laser pulses.
