LASER LIGHT SOURCE UNIT, CONTROL METHOD THEREFOR, AND OPTICAL ACOUSTIC IMAGE GENERATING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a laser light source unit capable of emitting pulse laser light with desired light emission intensity even when wave lengths are different from each other.SOLUTION: In emitting pulse laser light with a wave length of 750 nm, only a high-voltage switch 74 is turned on and only a first flash lamp 52 is turned on to excite a laser rod. In emitting pulse laser light with a wave length of 800 nm, high-voltage switches 74, 84 are turned on and both of a first and a second flash lamps 52, 53 are turned on to excite the laser rod.
