摘要 | An optical integration unit (40) comprising a light emitting unit (1) for oscillating a plurality of laser beams with different wavelengths, a wavelength plate (5), a polarization hologram element (2) for diffracting a first laser beam oscillated from a light source (1a), and a non-polarizing hologram element (3) for diffracting a second laser beam oscillated from a light source (1b). The wavelength plate (5) is formed so as to act as a ≶r /4 plate on the first laser beam and as a ≶r plate or a ≶r /2 plate on the second laser beam. |
其他摘要 | 一种光学集成单元(40),包括用于振荡具有不同波长的多个激光束的发光单元(1),波长板(5),用于衍射从光振荡的第一激光束的偏振全息元件(2)源(1a)和用于衍射从光源(1b)振荡的第二激光束的非偏振全息元件(3)。波长板(5)形成为在第一激光束上作为≶r/ 4板并在第二激光束上作为plater板或≶r/ 2板。 |
