摘要：

Monolithic, all-fiber PM optical amplifiers have been investigated regarding components performance, amplifier design and narrow line-width amplification. PM-based components performed very well, the pump/signal combiner in particular handling > 300W pump power and still maintaining the PER of the input signal. A co-pumped amplifier configuration was chosen based on reliability and potential SBS mitigation (i.e. fiber length after the active fiber output). This system based on PLMA-YDF-25/400 fiber appeared to give the best output power (155W-177W, depending on the length of passive delivery fiber), PER (similar to 17 dB) and excellent beam quality (M-2 = 1.1). Altering the fiber temperature and length were necessary to provide the best results.
