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

This invention describes the observation and characterization of a new type of stimulated scattering in a multi-photon absorbing medium which offers significant operational improvements in precision laser applications.

Brillouin scattering (state of the art) requires a very narrow spectral line width of the input laser pump (<0.01 cm-1). Only single longitudinal-mode lasers, often very expensive, can offer such narrow spectral line width. The invention can offer significant cost savings in these applications, as it does not require a narrow spectrum width. It requires minimum pump laser intensity, much lower than other existing stimulated scattering methods, thereby reducing manufacturing, component and operational costs.

Brilloui n scattering also possesses an inherent a phase shift which it introduces to present commercial devices. This invention utilizes Rayleigh scattering that results in no phase shift, substantially improving the quality of wave front restoration fideli ty.
