A common path interferometer for stimulated Raman scattering (SRS) and coherent anti-Stokes Raman scattering measurements (CARS)

摘要

A detailed description of a common path interferometer is given for CARS and SRS applications. In thisinterferometer, both probe and reference arms are separated in time and polarization by a birefringent crystal.In order to generate the pump pulse a Ti:Sa laser centered at 808 nm is used, as for the Stokes pulses aNd:YVO centered at 1064 nm is used, both lasers are synchronized in phase and frequency at a repetition rateof 80MHz. Acetone is employed for analysis and detection in this experiment, with a extinction ratio of1/250, a temperature heating control system is developed for the calcite birefringent crystals with a precisionof de ±0.01°C as well as an analysis of the contributions of both processes CARS and SRS by using a lock-inamplifier.© (2012) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
