Features

Broadband Supercontinuum from Phonic Crystal Fiber

In this solution a Phonic crystal fiber is used to generate broadband Supercontinuum that can be used as a Stokes pulse. Shown is a block diagram of the experimental setup with the following components: FI – Faraday isolator, 1/2 WP – half wave plate, BS – beam splitter, RELP – razor edge long pass filter, LP – long pass filter, SCG-800 – supercontinuum generation kit, FO – focusing objective, CO – collimating objective, SP – combination of short pass filters, FM – flip mount, PMT – photomultiplier. Our CARS Microspectrometer application note provides detailed information on set up, alignment and components used in this experiment.

Coherent Anti-Stokes Raman Scattering

An energy diagram of the CARS process is shown. The CARS signal is resonantly enhanced when the difference between the pump ωρ and Stokes ωS frequencies matches a vibrational transition ΩΡ of the molecule.

Broadband CARS

The combination of spectrally narrow picosecond pulse as a pump ωρ and probe ωρ’ and a broadband femtosecond pulse as Stokes is the basis for broadband CARS.
