We fabricated a novel quasi-phase-matched frequency converter, using a zigzag optical beam path in a thin, polished parallel plate. Second-harmonic generation experiments demonstrated angle-tuned output at 4.6 to 5.3μm in GaAs and 1.7 to 2.0μm in ZnSe crystals when pulsed infrared laser sources were used.
