Abstract: A Q switch is vibrated by applying a first voltage, and pulsed laser light is emitted by applying a second voltage to the Q switch at a point in time at which a preset delay time has passed from the start of emission of excitation light. Then, in this case, a time which is within a period, for which the vibration of the Q switch continues, and at which the intensity of the pulsed laser light periodically changing due to the vibration of the Q switch is maximized in a case where a point in time of application of the second voltage to the Q switch is changed is set as the delay time.

Abstract: After light has been output to a subject to be examined, a photoacoustic wave induced in the subject by the output light is detected. It is assumed that at least one virtual detector element is present outside of a real detector, and dummy data corresponding to the at least one virtual detector element are added to photoacoustic data in which pieces of data of the photoacoustic wave detected by the detector are arranged in accordance with the positions of detector elements. A photoacoustic image is generated by reconstructing the photoacoustic data to which the dummy data have been added by using a Fourier transform method.

Abstract: Disclosed is a laser device which can emit light having first and second wavelengths, having the advantage of increasing laser efficiency without causing an increase in cost. A flash lamp irradiates excitation light onto a laser rod. An optical resonator includes a pair of mirrors facing each other with the laser rod interposed therebetween. A wavelength switching unit includes a long path filter which transmits light having a wavelength equal to or greater than a first wavelength. The wavelength switching unit inserts the long path filter on the optical path of the optical resonator when the wavelength of laser light to be emitted is the first wavelength.

Abstract: To obtain an absorption distribution from a detected signal with a practical device. Light is applied to a subject, and a photoacoustic signal generated in the subjectA photoacoustic is detected. From the detected photoacoustic signal, a light differential waveform, which is a differential waveform of a temporal waveform of the light applied to the subject, is deconvolved. As a result of this deconvolution, an absorption distribution is obtained.

Abstract: A pulse laser beam is emitted in a desired wavelength sequence using a laser light 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. The rotation control unit 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. An emission control unit irradiates the laser rod with excitation light, and then 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.

Abstract: A probe transmits acoustic waves toward a subject. After transmission of the acoustic waves, the probe receives reflected acoustic waves of the transmitted acoustic waves. Whether the probe is in contact with a subject is judged based on the received reflected acoustic waves. The probe irradiates light toward the subject when it is judged that the probe is in contact with the subject. After the light is irradiated, acoustic waves generated within the subject due to the light being irradiated are received. A photoacoustic image is generated based on the received acoustic waves generated due to the light being irradiated.
