Hi, does anybody who knows the applications of backward type wave tell the detail of them? thank you very much!

It is the mechanism behind SBS, yes. For media where the refractive index is a function of the Intensity of the optical field, a suitably intense laser beam will form a temporary grating in the sense that it will vanish once the laser beam is removed.Tide said:Claude,
That sounds like stimulated Brillouin scattering.
