Abstract : After this grant was awarded and the matching fund was provided by Bowling Green State University, we purchased a YAG-laser-pumped optical parametric oscillator, which consists of three major components. We have optimized our multilayer structures for surface-emitting second-harmonic generation, transversely-pumped counter-propagating optical parametric amplification, and difference-frequency generation. We are currently characterizing this sample using our new laser system. The parametric processes will enable us to efficiently generate coherent light in the mid-infrared domain. Recently, we proposed backward optical parametric oscillators, amplifiers, and second-harmonic generation. Most recently, we observed backward second-harmonic generation in these crystals.
