我们报告了在周期性畴反转LiTaO3波导中，通过光栅反馈技术稳定的激光二极管倍频产生高功率和稳定的蓝光。由于质子交换和快速热处理形成的深畴反转区域和强波导限制，已经获得了高效率的二次谐波产生（SHG）。采用光栅反馈技术通过波导锁定激光二极管的振荡波长，实现了8 mW稳定的蓝色二次谐波。
We report high power and stable blue‐light generation by frequency doubling a laser diode, stabilized by a grating feedback technique, in a periodically domain‐inverted LiTaO3 waveguide. Due to the deep domain‐inverted regions and strong waveguide confinement formed by proton‐exchange and a quick heat treatment, high efficiency second harmonic generation (SHG) has been obtained. Locking the oscillation wavelength of a laser diode through the waveguide by a grating feedback technique, 8 mW of stable blue SHG has been demonstrated.
