≤ 2.405
V-Number @ 1070 nm
Normalized frequency of the core: at 2.405 or below, the fiber is single-mode.
Description
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.
Features & Benefits
- Single-mode operation and low splice loss with passive matching fibers
- Photodarkening-free-ensures stable long-term operation
- Wide, flat absorption from 910 nm to 970 nm-reduces pump cooling requirements ansd allows 940 - 960 nm pumping
Applications
- Pulsed fiber lasers: gaoin media in preamplifiers or low power amplifiers
- Material processing: Laser marking, laser engraving, micromachining and welding
