ABSTRACT:
An optical wavelength converter apparatus that employs quasi-phase-matched parametric interaction or sum/harmonic frequency generation of electromagnetic radiation within a slab of optical material. The optical wavelength converter apparatus uses a zig-zag electromagnetic beam path in an optically flat and parallel slab on which total internal reflection from upper and lower surfaces provides a phase shift for phase matching for each leg of the zig-zag path.
