Liekki T-YB1200-4/125 is a highly doped ytterbium fiber for low noise, low nonlinearity preamplifiers and lasers. It is a single-clad fiber for core-pumped applications. This fiber is ideal for use as a preamplifier in a fiber amplifier chain with double cladding fiber acting as a power amplifier.
This fiber's telecom-like geometry makes it compatible with low-cost pump diodes, standard single mode passive fibers, and standard telecom connectors and splicing techniques.
