| Abstract: | This thesis describes developments that have been made on two applications of spectral shaping for imaging and spectroscopic analysis. The first application is based on coherent anti-Stokes Raman scattering (CARS). CARS provides label free chemical selectivity based on a compound‟s vibrational resonances, it is often used as a chemically selective imaging tool. The CARS signal is, through the anti-Stokes shift, free from one photon fluorescence background. In our system CARS is used for the detection of compounds with vibrational resonances in the fingerprint region 2800 cm-1 to 3200 cm-1. By using spectral shaping we are able to remove non-resonant background from our signal and obtain an enhanced contrast for specific compounds |
