Abstract

How to decrease the threshold and how to improve the quality of output beam of stimulated Brillouin scattering (SBS) phase-conjugation cavity is a problem. The output characteristic of compound phase-conjugate cavity with good beam mode is reported. The output energy of single pulse is 13.35 mJ with 15 ns of widths, and the divergence angle is 0.6 mrad. The results of pulse widths and output energies and beam profiles are given, indicating that using the compound cavity is a useful and easy method to improve the quality of beam mode.
