Abstract: A puncture needle is at least partially inserted into a subject. An optical fiber guides light with a first wavelength and an optical fiber guides light with a second wavelength. The light guided by the optical fiber is emitted from a first light emitting portion and the light guided by the optical fiber is emitted from a second light emitting portion. A light absorption member absorbs the light with the first wavelength emitted from the first light emitting portion to generate photoacoustic waves and transmits the light with the second wavelength emitted from the second light emitting portion.

Abstract: Provided are a photoacoustic image generation apparatus and an insert that can evaluate whether a plurality of materials with different absorption wavelengths are present in the vicinity of a puncture needle, without preparing a plurality of light sources. A puncture needle is at least partially inserted into a subject. An optical fiber guides light with a first wavelength. A light emitting portion emits the light guided by the optical fiber. A light absorption/conversion member absorbs the light with the first wavelength emitted from the light emitting portion and converts the light with the first wavelength into light with a second wavelength. In addition, the light absorption/conversion member generates photoacoustic waves with the conversion into the light with the second wavelength.
