Low-cost and compact second harmonic laser for photoacoustic imaging.

ABSTRACT: Photoacoustic imaging (PAI) combines the high contrast of optical imaging with the high resolution of ultrasound imaging, which has garnered significant attention in applications such as vascular imaging and liver function reserve (LFR) assessment. The realization of low-cost and miniaturized light sources is a crucial development direction for the future application and commercialization of PAI. Traditional high-power pulsed lasers (hundreds of millijoules range) are bulky and expensive, although light-emitting diodes (LEDs) are lower in cost and more compact, their output energy is relatively weak (microjoules range), and their pulse width is wide (tens of nanoseconds range), making them unsuitable for high-resolution PAI of clinical application. This paper proposes a low-cost, compact P
