Coherent anti-Stokes Raman scattering (CARS) typically involves the interaction of the material with three (pump, Stokes, and probe) laser beams. Recently developed by the Silberberg group [1], single-beam CARS takes all pump-Stokes-probe fields from one ultra-broad bandwidth laser source and removes the complexities involved when using several laser pulses and has become increasingly popular in biomedical...
Self phase modulation in hollow waveguide filled with noble gases have been successfully used to produce ultra-broad bandwidths. The intense spectral phase distortions produced by self phase modulation have previously been compensated by prism pairs and adaptive pulse shaping. Here we demonstrate the generation of 4.8 fs, 200 muJ intense laser pulses by multiphoton intrapulse interference phase scan...
We introduce an improved method for standoff chemical detection of films and residues on solid targets which scatter or reflect the incident light using single-beam Coherent anti-Stokes Raman Scattering.
Binary phase shaping is applied to single-beam CARS spectroscopy of gas mixtures, such as ambient air, and is shown to provide mode-selectivity and enhanced non-resonant background suppression capability when compared with the original technique.
We report a method for generation of ultra-broad bandwidth laser spectrum using self-phase modulation in the argon-filled hollow waveguide and pulse compression with multiphoton intrapulse interference phase scan technique.
We report a new method for standoff chemical detection based on single ultrafast pulse excitation for remote coherent anti-Stokes Raman spectroscopy. Mode-selective and background-free excitations were achieved through optimal binary phase pulse shaping.
