Abstract

A blazed gain grating in a four-level atomic system is theoretically demonstrated. This grating is based on the spatial modulation of Raman gain, which is created by an intensity mask in the signal field. Due to the modulo-2π phase modulation, the majority of energy in the amplified probe beam can be deflected into the first-order direction, and a diffraction efficiency higher than 100% is predicted. When an intensity mask having two symmetric domains is adopted, this proposal can give a further possibility of all-optical beam splitting.
