OPTICAL FIBER FOR LASER GUIDE AND LASER GUIDE INCLUDING THE SAME

摘要

An optical fiber (100) for a laser guide used for transmitting laser ligh t comprises a optical fiber body (110) having a core (111) and a clad (112), and a quartz chip (120) which is integrally provided on the light entrance end side of the optical fiber body (110) and at least an optical waveguide p ortion of which is formed of pure quartz glass. A light entrance end surface of the quartz chip (120) is subjected to surface melting.
