Photoacoustic imaging is a valuable high-contrast in vivo imaging technique for pre-clinical and clinical applications. This technique uses laser-induced ultrasound.

Ultrasound signal is generated in tissue, when it absorbs laser light and expands thermo-elastically,  and their waves are detected by ultrasonic transducers. 2D or 3D images are then reconstructed from the accumulated data.

Laser sources for photoacoustic imaging include LPSS OPOs, DPSS OPO systems.
