摘要	A semiconductor laser emits semiconductor laser light with TM-mode oscillation. The emitted semiconductor laser light is collimated by a first collimating lens, passes through a Brewster plate that is arranged so that the direction of Brewster plane's p-polarized light is in alignment with the direction of polarization of the emitted semiconductor laser light, and is coupled to an incident portion of a wavelength-conversion waveguide by means of a focusing lens. While being guided through the waveguide, the emitted semiconductor laser light is converted into second-harmonic light by means of a polarization inversion region. Semiconductor laser light emanating from an emitting portion of the waveguide reflects from an output mirror towards a diffraction grating, for modulation in wavelength. Second-harmonic light emanating from the emitting portion of the waveguide is outputted from the output mirror.
其他摘要	半导体激光器发射具有TM模式振荡的半导体激光。发射的半导体激光由第一准直透镜准直，穿过布鲁斯特板，布鲁斯特板布置成使布鲁斯特平面的p偏振光的方向与发射的半导体激光的偏振方向对准，并且耦合借助于聚焦透镜到波长转换波导的入射部分。在被引导通过波导时，发射的半导体激光通过偏振反转区域被转换成二次谐波光。从波导的发射部分发出的半导体激光从输出镜朝向衍射光栅反射，用于波长调制。从输出镜输出从波导的发射部分发出的二次谐波光。
