Abstract

An object information acquiring apparatus is used which includes a laser medium that oscillates laser light, an excitation source that excites the laser medium, a voltage accumulator that applies a voltage to the excitation source, a voltage supplier that supplies a voltage to the voltage accumulator, a voltage controller that limits a maximum supplied voltage from the voltage supplier, a receiver that receives a photoacoustic wave generated by an object irradiated with the laser light, and a constructor that acquires characteristic information relating to the object in use of the photoacoustic wave, wherein the voltage controller compares a measured voltage value obtained by implementing division of a supplied voltage from the voltage supplier with a reference voltage value defining the maximum supplied voltage.
