Repetition frequency modulated fiber laser for coherent anti-Stokes Raman scattering

Abstract

The dual-comb coherent anti-Stokes Raman scattering (CARS) technique has been proposed and developed for many years with various applications. It maps the spectral information to the time domain and resolves Raman peaks by scanning the relative delay of the pulse pair. One main drawback of this method is the low duty cycle. The span of scanning is far larger than needed, leading to a massive waste of time and energy. In this Letter, a dual-comb fiber laser system with fast repetition modulation ability is proposed and demonstrated. It can detect the relative delay via an asymmetric sum-frequency-mixing method and flip the repetition frequency difference at the exact time to increase the duty cycle by several hundred times. Consequently, it is expected that the detection efficiency is greatly enhanced compared to traditional dual-comb systems for CARS measurements.
