The high-power single-mode erbium-doped fiber
amplifier (EYDFA-HP), based on the laser amplification principle of
the optical signal in the erbium-doped fiber, adopts a unique
multi-stage optical amplification design and a reliable high-power
laser cooling process to achieve high-power laser output in the
wavelength range of 1540~1565nm. It has the advantages of high power
and low noise, and can be used in optical fiber communication, laser
radar, etc
