Outline of Final Research Achievements

Quasi-phase matching can realize various and arbitrary wavelength conversion by fabrication of artificial periodic structure in the nonlinear crystal. In this research, new scheme in the QPM was investigated and demonstrated by using chirped structure or periodic laminar structure. Collaborating works by using the newly developed QPM device were done.
Also, crystal quartz was newly investigated for intense laser pumped wavelength conversion.
