Quasi -molecule laser device with optical path transmission structure

The utility model discloses a quasi -molecule laser device with optical path transmission structure, including seed chamber, enlarged chamber and optical path transmission structure, the seed chamber is used for exporting seed laser, and enlarged chamber is used for enlargeing the energy of seed laser, optical path transmission structure are used for guiding the transmission of laser, and wherein, the optical path transmission structure includes first triangular prism, second triangular prism and third triangular prism. The utility model discloses an adopt special angle triangular prism, and take the special mode of putting to the triangular prism, realize the poor compensation mutually of P light sum S light phase, make the optical path transmission structure can not produce additional phase difference, the laser polarization state that reaches the final output and the seed laser polarization state from discharge cavity output unanimously, keep the stable purpose of laser polarization state.
