<p>A high power laser transmitting fluoride glass fiber having an enhanced 2.94- mu m laser damage threshold value, in which, of the core with a high refractive index and the cladding with a low refractive index, at least the core is formed of fluoride glass which contains fluorine (F) as a component, the fluorine being substituted with 0 to 4.1 mol% of bromine (Br), chlorine (Cl), or bromine and chlorine. The optical fiber of the present invention may have its core formed of fluoride glass and its cladding formed of fluorine-containing resin, the core glass comprising 70 to 80 mol% of fluorine (F) and 0 to 4.1 mol% of bromine (Br), or chlorine (Cl), or bromine and chlorine.</p> |
