ABSTRACT:
The invention provides structure and method for improving the efficiency of nonlinear optical processes where two light beams interact in a material to produce an output beam at a new frequency. Effective phase matching is accomplished by periodically removing the output beam energy so that it does not destructively interfere with the input. The invention can also be utilized to increase the efficiency of optical devices where partial phase matching is present without further adjusting the phase of the beams involved in the nonlinear interaction. The invention also provides effective beam phase matching where the beams passing through the nonlinear material cannot normally be phased matching by present methods.
