We developed a high-resolution LCOS-SLM spectral filter for a 1.65 μm optical frequency comb and achieved spectral peak generation with a resolution of 65.2 pm by optimizing the optical system. The generated spectral peaks were amplified using a fiber Raman amplifier while maintaining their narrow linewidth, resulting in a peak linewidth of 92 pm and a spectral peak brightness of 16 mW/nm. Furthermore, by combining the amplified spectral peaks with a Fabry–Perot filter having a 30 GHz free spectral range, we demonstrated selective extraction of a single comb mode. These results show the feasibility of generating high-intensity spectral peak combs and extracting arbitrary comb modes for high-sensitivity spectroscopic applications.
