Spatial filtration of optical signals by nonlinearly absorbing elements
Yu. M. Gryaznov, A. A. Chastov
Abstract:
The method for increasing the signal/noise ratio with the aid of a nonlinear spatial bleachable filter was analyzed and tested in practice. The signal/noise ratio was increased by two orders of magnitude using a solution of bromated gallium phthalocyanine and ruby laser radiation.
