Paper Abstract
We present a dual-wavelength laser using stimulated Raman scattering (SRS) effect which have high pulse repetition rate for fast functional photoacoustic (PA) imaging. This laser has a high pulse repetition rate of 300 kHz and high pulse energy more than 200 nJ. We periodically modulated the electro-optic modulator voltage from 0 to 168 V to switch the polarization of the output light. Two different pulse lights separated by polarization switching were used to generate different SRS peaks using Raman fibers with lengths of 5 and 20 m. The operating wavelength of this laser was switched to 545 nm and 603 nm using SRS effect and polarization switching. Wavelength dependent fast functional PA images of blood vessels and gold nanorods were obtained using a dual-wavelength switchable SRS pulsed-laser.
