Abstract

A high power amplifier silica glass material is provided wherein photo darkening due to high optical flux is reduced considerably. The conventional counter part amplifier and laser based on conventional silica glass material have a problem in that their characteristics are deteriorated with the elapse of time due to photo darkening. The new fibre amplifier and laser silica glass material shows through reduction of the non-binding oxygen electron concentration less photo darkening. This is achieved through hydrogen or deuterium load of the amplifier glass material or by co-doping with phosphorous P4O8-x(OH)4+2x, (0 x 2).
