LIEKKI® Large Mode Area Passive Fibers

LIEKKI® passive fibers are especially designed and manufactured to match the optical guiding properties of LIEKKI® large mode area Ytterbium doped fibers. This enables optimal mode coupling with minimal splice loss for maintaining the power and excellent beam quality between all elements of a fiber laser or amplifier. High-quality Fiber Bragg Gratings can be written into all LIEKKI® passive fibers. 
LIEKKI® passive fibers are available in single cladding, double cladding (DC), single cladding polarization maintaining (PM) and double cladding polarization maintaining configurations.
