Fibre optique spéciale

The Yb-DCOF-15/125-08-2.7-PM fiber is a PM, double clad fiber, featuring a 15 µm core diameter, with a low photodarkening core glass host allowing long term efficiency of performances. Its near-diffraction-limited output design makes it the perfect choice for laser applications and pulsed fiber lasers and amplifiers requiring superior beam quality. This fiber also features a very high absorption level - 2.7 dB/m at 915 nm.
