Research Abstract

1. We have optimized device fabrication process for AlGaAs waveguiding QPM devices. Corrugations, a major cause of the large propagation loss, are shown to be caused by the anisotropic surface diffusion of Ga atoms. We have achieved almost corrugation-free regrowth by using a low-temperature MBE process.
2. GaP sublattice reversal epitaxy has been successfully demonstrated for the first time. AlGaP-based QPM devices can be used with high-power 1-μm pump lasers because of their small two-photon absorption coefficients.
3. Conversion efficiencies attainable in high-index-contrast AlGaAs waveguiding QPM devices has been theoretically investigated for the first time. We have shown that normalized conversion efficiencies over 40,000 %/W/cm2 can be obtained for SHG for 1.5 μm fundamental light.
4. We have proposed a new QPM scheme in bent waveguides utilizing periodical sign reversal with periodic change of propagation direction by 90° instead of periodical inversion of crystal structures.
5. We have investigated polarity characterization techniques of GaN crystals and succeeded in fabricating periodically inverted GaN films. In addition, nonlinear optical properties of GaN and SiC have been characterized in detail, by using high quality bulk single-crystalline samples.
6. A 300-W CW operation of Yb:YAG/ceramic YAG hybrid edge-pumped laser has been demonstrated. By optimizing laser cavity configuration, much improved transverse mode characteristics, M^2 = 17, has been achieved for 230-W CM operation.
