摘要: The present application discloses an optical fiber amplifier. By adopting two gain optical fibers with different absorption coefficients as an amplification stage of optical fibers, a damage to a device and an impact on system stability caused by ASE generated by optical fibers can be avoided, and at a same time, utilization efficiency to pump light can be improved. On another hand, an original two-stage amplification can be reduced to a single-stage amplification in the present application, which can effectively reduce requirements for timing, take into account improvement of stability and performances of lasers, and reduce production cost of the lasers.
