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 tunable wavelength 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 lamp-pumped tunable wavelength and diode-pumped solid-state (DPSS) tunable wavelength OPO systems.
