ATOM INTERFEROMETER GYROSCOPE BASED ON SINGLE RAMAN LASER BEAM

摘要

The present invention provides a laser processing apparatus comprising: a Raman laser generating unit for generating a Raman laser beam; A polarization beam splitter disposed on a path of the Raman laser beam generated by the Raman laser generator; A first quarter wave plate disposed on a path of the Raman laser beam passed through the polarized beam splitter and converting the Raman laser beam passing therethrough into circularly polarized light; An acoustic optical modulator arranged on a path of the Raman laser beam passing through the first quarter wave plate to cause a diffraction of the incident Raman laser beam; A reflector configured to reflect the Raman riser beam having passed through the acoustooptic modulator to the acoustooptic modulator; The first quarter wave plate, and the polarized beam splitter, and then the Raman laser beam is converted into a vertical polarized light by passing through the Raman laser beam, An optical fiber part for transferring; And an optical fiber unit disposed on a path of the Raman laser beam, the Raman laser beam being incident on the optical fiber unit, the Raman laser beam being expanded in a predetermined section along a path of an atomic beam traveling in a direction crossing the Raman laser beam, And a Raman laser beam expander configured to provide an interference region of the atomic beam.
