Abstract:We present a wavelength‐switchable, synchronously pumped Raman fiber laser based on a dual‐cavity design operating in the 1.7 µm region, specifically developed for multispectral photoacoustic microscopy (PAM). By precisely engineering the lengths of the pump laser cavity and the Raman laser cavity and meticulously controlling the modulation frequency, we achieved synchronous pumping by synchronizing the Stokes light within the Raman laser cavity to have the identical round‐trip time as the pump light.
