We have developed a high-speed wavelength switchable laser for functional photoacoustic microscopy. Fast and random wavelength switching is achieved by using an acousto-optic tunable filter as an output coupler. Wavelength and pulse width can be instantly controlled with changing the electronically-driven diffraction grating without mechanical motion.
