摘要

为发展紫外激光器，设计并制备了氮化镓准相位匹配晶体。采用双极性选择性面积生长(DP-SAG)法制备GaN-QPM晶体。通过光学测量，证实了由于相位匹配而产生的二次谐波。

Fabrication of GaN-QPM crystals for slab waveguide type wavelength conversion devices

Quasi phase matching (QPM) crystals using GaN were designed and fabricated for the development of ultraviolet lasers. GaN-QPM crystals were fabricated by the double polarity selective area growth (DP-SAG). As a result of optical measurement using such fabricated crystals, second harmonic generation (SHG) due to phase matching was confirmed.
