This phosphosilicate fiber is ideal as a gain medium for lower power amplifiers or the pre-amplifier stage and is mainly used in a MOPA configuration of a pulsed fiber laser. On top of all the benefits found in a phosphosilicate fiber (photodarkening-free and high absorption), this fiber shows high energy saturation, which is essential for applications such as laser marking and engraving.
