Abstract

The present invention discloses polarized light beam splitting double reflection method and polarized light beam splitting prism, and belongs to the field of optical device technology. The present invention features that light beam is radiated to crystal interface and bireflected to split into two planar light beams with perpendicular vibration directions before being emitted from the outgoing plane. The polarized light beam splitting prism consists of one prism of one single uniaxial crystal and one prism of two uniaxial crystals, and has optical axis perpendicular to the incident plane and angle between the incident plane and the reflecting plane of 45 and 90 deg. It has the functions of several devices and important application in laser technology, optical test, optical modulation, etc.

Description

technical field [0001] The invention discloses a double-reflection polarized beam splitting method and a polarized beam splitting prism, belonging to the technical field of optical devices. Background technique [0002] Polarizing devices are important devices in the field of laser technology and polarization application technology, and polarizing beam splitting prisms are an important category of polarizing devices. Its research and development are of great significance to the development of modern optical technologies such as optical communication, optical information processing, optical testing, laser technology and optical computing. Before the present invention was made, the functions of conventional polarizers were single, and multiple functions such as polarization, beam splitting, and beam steering could not be integrated into one body, which brought a lot of inconvenience to experiments and applications. The development of laser and light modulation application tec...
