Coherent Anti-stokes Raman Spectroscopy (CARS) and Stimulated Raman Scattering (SRS) are powerful and label-free techniques for chemical identification of molecules by their characteristic vibrational and rotational modes. TOPTICA provides a variety of pump and Stokes laser configurations for CARS and SRS covering the entire fingerprint region from 450 – 12500 cm-1. The pump and Stokes laser are optically synchronized and their relative timing can be adjusted using a built-in optical delay.
