Supercontinuum Laser for Spectroscopic Photoacoustic Imaging of Lipids in the Extended Near-Infrared Region

The ability of spectroscopic photoacoustic imaging to enable functional information on top of the structural information of the tissue makes it a promising tool for detection and monitoring of numerous diseases. In the current work, we demonstrate a cost-efficient high-power supercontinuum laser source based on a telecom range diode laser system and few meters of a standard optical fiber for spectroscopic photoacoustic imaging of lipids in the extended near-infrared region.
