This phosphosilicate fiber is ideal as a gain medium or lower power amplifiers on 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 (high saturation energy, photodarkening-free performance and high absorption), this fiber is singlemode operation and very low splice loss whean matching with standard fibers such as HI 1060.
Yb-doped fiber for pulsed lasers
