| Outline of Final Research Achievements |
Despite the strong needs for the semiconductor lithography and medical applications, still the semiconductor laser with a deep-UV emission has never been realized. In this work, novel methods for emitting deep-UV has been proposed, via the second harmonic generation in UV regime, pumped by blue laser diodes, based on the wavelength conversion process taking advantage of strong optical nonlinearity in AlN. Also, the elemental technologies for the device fabrication, design as well as the optical investigation have been developed.
