    Abstract: A photoacoustic medical-imaging device includes a wavelength conversion assembly (108) configured for outputting laser pulses at a targeted wavelength. It also includes a photoacoustic probe configured for acoustic coupling to a patient, for directing the pulses, and for acquiring, in response, radiofrequency data for photoacoustic imaging. It may include an optical fiber bundle (120) that comprises an optical fiber having an input end, and be configured for illuminating, with a homogenous beam, so as to conform to an acceptance angle (160) of the fiber at that end. It may also include a light collimator, and a diffuser for receiving the outputted laser pulses from the collimator. The diffuser may be configured for spreading a focus of the pulsed light (148) over an input aperture of the bundle to equalize the light received by different constituent optical fibers of the bundle. The assembly may include a dye cell (132), and may reside in the probe.
