1. An optical-resolution photoacoustic microscopy (OR-PAM) system for visualizing water content in the deep tissue of biological organisms, comprising as an input an all-fiber hybrid optical parametrically-oscillating emitter operating in a range from 1877 nm to 1980 nm, wherein the hybrid structure uses nonlinear fibers with stable phase matching and rare-earth fibers.
