FastFBR is a line polarization-maintaining fibers based on the INO low photodarkening core chemistry with a refractive index profile designed to ensure an excellent output beam quality. The FastFBR line is thus the perfect choice for pulsed fiber laser applications requiring long-term reliability and optimal output beam profile.
There is a FastFBR Yb-doped fibers for any amplification stage of your pulsed laser system:
Low to Medium Power
The Yb401-PM fiber is a single-clad and truly single-mode PM fiber featuring a 6.0 μm MFD @ 1064 nm, a core absorption of 140 dB/m @915nm. This fiber is well adapted for low power pulsed amplifiers pumped using single-mode laser diodes.
The Yb-MCOF-10/125-08-1.6-PM is a multi-clad PM fiber having a 10µm single-mode core and a cladding absorption of 1.6dB/m @915nm.
The Yb-DCOF-15/125-08-2.7-PM is a double-clad PM fiber having a 15µm core and a high cladding absorption of 2.7 dB/m @915nm.
The INO Multi-Clad Optical Fibers (MCOF) feature a confined core for selective amplification of the fundamental mode and a patented depressed cladding for enhanced suppression of higher order modes, offering an output M2 lower than 1.15, making it perfectly suited for applications requiring superior beam quality. The INO multi-clad large-mode-area fibers feature a 35µm core with 0.07NA , a 250µm cladding and come in two versions:
The Yb-MCOF-35/250-07-0.9-PM, with an absorption of 0.9dB/m @ 915nm.
The Yb-MCOF-35/250-07-2.5-PM, with an absorption of 2.5dB/m @ 915nm.
To reach the highest output power with an Yb-doped optical fiber for ultrafast laser applications, we offer the FastFBR taper:
The Yb-MCOF-35/250-56/400-07-2.2-T0.7-PM is a tapered fiber designed for an output M² lower than 1.2, making it the perfect choice for high power pulsed applications requiring superior beam quality. It features a confined core for selective gain amplification of the fundamental mode, and a patented depressed-cladding design for enhanced suppression of higher order modes. This tapered fiber has a linear absorption of 2.2 dB/m @915nm and an output core diameter of 56µm.
