Abstract: Provided is a photoacoustic imaging device including: a light source unit which generates an ultra-broadband pulsed laser beam and outputs the ultra-broadband pulsed laser beam; a filter unit which filters narrowband pulsed laser beams having predetermined different wavelength bands from the ultra-broadband pulsed laser beam to selectively extract the narrowband pulsed laser beams and outputs the narrowband pulsed laser beams as pulsed laser beams for photoacoustic imaging; and a PA (photoacoustic) unit which receives the pulsed laser beams for photoacoustic imaging to irradiate a measurement object with the pulsed laser beams for photoacoustic imaging and receives photoacoustic signals generated from the measurement object.
