摘要： Disclosed are an apparatus and a method for controlling phases of beams to make relative phases of the beams “O” in a beam splitting amplification laser using a stimulated Brillouin scattering phase conjugate mirror. A procedure of making a phase difference between laser beams reflected from the phrase conjugate miror “O” comprises a first step of inputting laser beams 104′, . . . , 114′ and 124′ reflected from the phrase conjugate mirrors to a light detector 150 through light path converters 131 and 132; a second step of using one of the reflected laser beams as a reference laser beam 104′ and making the reference laser beam intefere with another reflected laser beam 114′; and a third step of detecting the interference result and finely driving piezoelectric elements 109 and 119 to control the positions of the reflectors 108, 118 and 128, to thereby make a phase difference between the laser beam 104′ and 104′ become “O”.
