This report deals with a simple method to tune the pulse-width for a single-mode Q-switched YAG oscillator by simply changing the inner distance of two-cell stimulated Brillouin scattering (SBS) systems. The SBS pulse is amplified as it is returning into the YAG medium and then output coupled by a quarter wave-plate and a cavity polarizer. This double-pass phase-conjugate configuration improves the laser beam quality. Less than 2 times diffraction-limited divergence is achieved. Pulses with 2--8ns tunable range and about 10mj pulse energy are obtained.
