Fiber optical parametric oscillators (FOPOs) are promising high-speed and broadband wavelength-tunable laser sources for stimulated Raman scattering microscopy. We previously reported a broadband wavelength-tunable (1200 cm^-1) FOPO that can be used for high-speed imaging in combination with a low-noise laser. Here, we report a FOPO increasing the output power up to 57 mW by improving the power spectral density of an Yb-doped fiber laser, which serves as the pump light.
