Stimulated Raman scattering (SRS) microscopy is a label-free and molecular-vibration-sensitive biological imaging method. It employs synchronized two-color pulses—known as pump and Stokes beams—whose frequency difference determines the specific molecular bonds that are probed. In our previous work, we developed a wavelength-tunable fiber optical parametric oscillator (FOPO) with a fixed repetition rate, enabling synchronization with a Ti:sapphire laser. However, this system used a free-space cavity, which required frequent alignment. In this study, we demonstrate a fiber cavity implementation of a wavelength-tunable FOPO with a fixed repetition rate, offering a stable and tunable source for SRS imaging. The cavity configuration demonstrates potential for realizing an all-fiber FOPO that is alignment-free and enables rapid wavelength tuning, making it a highly promising light source for future biomedical imaging applications.
