ABSTRACT:
Producing high efficiency laser wave mixing and laser harmonic generation laser beams by reconstruction of fundamental and second harmonic laser beams from a frequency doubling crystal by use of a pair of optical wedges. The optical wedges are positioned with their angled surfaces facing each other with substantially 180 degrees of relative rotation and separated at a predetermined distance. The two spaced apart laser beams enter the first optical wedge from the frequency doubling crystal and the two beams converge after exit the first wedge. The converged laser beams enter the second wedge and exit therefrom, forming a coaxially overlapping single beam which is to be used for high efficiency generation of a higher order harmonic laser beam.
