Abstract: A probe has a light guide unit that guides the measurement light, an acoustic wave detection unit that detects a photoacoustic wave, and a storage unit that stores light intensity profile information that represents the light intensity profile of the measurement light emitted by the probe, and transmits a signal of the photoacoustic wave detected by the acoustic wave detection unit to the signal processing unit in a state in which the probe is mounted in the apparatus body. The apparatus body has a reading unit that reads the light intensity profile information from the storage unit, and the intensity adjusting unit adjusts the intensity of the measurement light employing the light intensity profile information read by the reading unit.

Abstract: Using a laser source unit, pulse laser beams having a plurality of wavelengths is switched and emitted. A Q switch is inserted into an optical resonator including a pair of mirrors which face each other with a laser rod interposed therebetween. A wavelength selection unit includes a plurality of band pass filters having different transmission wavelengths, and selectively inserts the plurality of band pass filters into a light path of the optical resonator. A trigger control circuit controls driving unit that drives the wavelength selection unit so that the band pass filters inserted into the light path of the optical resonator are switched at a predetermined switching speed. In addition, the trigger control circuit causes the laser rod to be irradiated with excitation light from a flash lamp, and then turns on the Q switch at a timing when the wavelength selection unit inserts the band pass filter.

Abstract: A flash lamp 32 excites a laser rod 31. A Q switch 35 which changes the loss of the optical resonator according to the voltage applied is inserted on the optical path of a pair of mirrors 33 and 34 forming the optical resonator. An optical path shutter 39 is provided on the optical path of laser emission light. In a first operation mode in which laser emission is performed, the optical path shutter 39 is opened and the voltage applied to the Q switch 35 is changed from a high voltage to, for example, 0 V to emit pulsed laser light after the flash lamp 32 excites the laser rod 31. In a second operation mode in which the laser emission is interrupted and waited for, the optical path shutter 39 is closed and the voltage applied to the Q switch 35 is, for example, 0 V.

Abstract: A pulse laser beam is emitted in a desired wavelength sequence using a laser source unit. A Q switch and a birefringent filter are inserted into an optical resonator including a pair of mirrors and facing each other with a laser rod interposed therebetween. The birefringent filter changes an oscillation wavelength of the optical resonator in association with rotational displacement. A trigger control circuit rotates the birefringent filter at a predetermined rotation speed depending on the number of wavelengths included in the wavelength sequence of the pulse laser beam to be emitted. In addition, the trigger control circuit irradiates the laser rod with excitation light, and turns on the Q switch at a timing when a rotational displacement position of the birefringent filter is set to a position corresponding to the wavelength of the pulse laser beam to be emitted, to cause the pulse laser beam to be emitted.
