LIEKKI Yb1200-4/125
Single mode ytterbium doped fiber
|
 |
|
| Product description |
|
|
LIEKKI Yb1200-4/125 is a highly doped ytterbium fiber for low noise,
low non-linearity preamplifiers and lasers. Its telcom-like geometry
makes the fiber compatible with low cost pump diodes and standard
single mode passive fibers. It makes an excellent preamplifier in a
fiber amplifier chain with double clad fiber acting as power amplifier. |
