Stimulated Raman scattering (SRS) microscope is a promising high-speed molecular vibrational spectroscopy in the fields of biology and medicine. In order to measure a broad Raman spectrum with high temporal resolution, a fast and widely wavelength-tunable light source is needed. In this report, we conducted SRS imaging with a fiber optical parametric oscillator (FOPO) which satisfies the requirements and a Ti:Sapphire laser, and report the successful measurement of a SRS spectrum through the automatic tuning of the wavelength of the FOPO.
