Abstract

We have performed analysis and measurements on a device which can selectively attenuate a coherent beam in the presence of an incoherent signal-bearing beam. Our calculations show that a rejection of 50 dB can be achieved for an optimum interaction geometry. Device measurements in the cw and pulsed regime are described.
