FIELD: physics.SUBSTANCE: light guide has a protective and hardening coating, an external quartz protective cladding; a depressive cladding; a light-guide core consisting of quarts glass, loading rods which guide linear birefringence in the light-guide core and the depressive cladding. The light guide additionally includes a second depressive cladding between the protective quartz cladding and the external boundary of the first depressive cladding in a region which is free from the loading rods. Radiation-proof properties are achieved by making the "Panda" light guide core from pure quartz glass.EFFECT: providing a light guide with small MFD dimensions and low loss of channelled polarisation modes.2 cl, 4 tbl, 8 dwg |
