Backward stimulated Rayleigh-Bragg scattering devices based on multi-photon absorbing materials and their applications

摘要

The present invention relates to a method and system of generating backward stimulated Rayleigh-Bragg scattering by focusing activating radiation through a multi-photon absorbing dye solution, thereby producing coherent output radiation with no measured frequency shift and measured pump threshold values independent of the spectral line width of the input activating radiation.
