Coherent broadband light generation with a double-path configuration. Academic Article uri icon


  • We generate broadband light by focusing two femtosecond pulses into a Raman-active crystal. By reflecting Raman sideband beams together with the two driving beams back to the same crystal (with a slight spatial offset), we generate sidebands covering a broader spectral range, compared to a single pass. In this novel double-path configuration, multiple Raman sideband beams interact with each other since the phase-matching condition is automatically fulfilled. This scheme enables an enhanced cascaded coherent anti-Stokes scattering process and also doubles the interaction length, thus it allows one to use relatively weak energy pump pulses and thereby avoid optical damage.
