Solid state lasers for wide-field CARS microscopy

We discuss the requirements for laser systems used in Coherent Anti-Stokes Raman Scattering (CARS) microscopy and particularly in its wide-field modification. While such laser parameters as wavelength, spectral width and frequency difference between pump and Stokes beams are similar for all CARS systems, requirements for pulse energy, repetition rate, pulse length and mode structure might be significantly different for scanning and wide-field approaches. We will present results obtained with a wide-field CARS microscope with non-phase matching illumination and compare its performance with other CARS microscopes. Objectives for the design of future laser systems for CARS microscopy will be outlined.
