| Abstract | We demonstrate a robust, simple, and compact all polarization-maintaining (PM) fiber laser source with a repetition rate of 79 MHz for broadband coherent anti-Stokes Raman scattering (CARS) spectroscopy based on impulsive excitation and narrowband probing. The careful dispersion management during the generation of pump pulses ensures efficient impulsive excitation, which is verified to cover an ultrabroad bandwidth exceeding 4000 cm–1. The employment of PM fibers enables the laser source to withstand external disturbances. This turn-key configuration can potentially simplify the implementation of many applications of CARS, such as spectroscopic histopathology, weaponized endospore detection, and precise thermometry of gases. |
