A doublepass configuration of MOPA system is realized by a diode pumped, single longitudinal mode Nd∶YAG master oscillator and three flashlamppumped YAG amplifiers with a phase conjugating stimulatedBrillouinscattering cell. Through a singlepass amplifiering of two amplifier cells and a tubular amplifier,the laser output energy of 10.59J, pulse duration of 4.76ns, divergency angle of 6mrad and 10Hz repetition rate are obtained.
