We have proposed and demonstrated a high-power C+L-band erbium amplified spontaneous emission source using an optical circulator with double-pass and bi-directional configuration, which can provide a high output power of 177.8 mW with a ripple of 5 dB and a wide line width of 81.0 nm (1525.1-1606.1 nm) without adding any external spectra-flattening components. This designed configuration is also considered relaxing resonant lasing for averaged power stability with +/- 0.013 dB, allowing high pumping efficiency of 32.8%.
我们提出并演示了一种采用双程和双向配置光循环器的高功率C+L波段铒放大自发辐射源，该源无需添加任何外部光谱平坦化组件，就能提供177.8 mW的高输出功率，纹波为5 dB，线宽达81.0 nm（1525.1 - 1606.1 nm）。这种设计配置还被认为可缓解共振激光，实现平均功率稳定性达±0.013 dB，泵浦效率高达32.8%。
