Study on a Novel Broadband High Power Source

报道一种新型的高功率宽带光源 ,它利用 1480nm激光器对掺铒光纤进行抽运 ,经啁啾光纤光栅反射后二次放大输出 ,其功率高达 1 41mW ,线宽为 10nm。该光源工作的线性区间对应的电流为 375～ 6 45mA。

A newly designed high power broadband source was reported. A 1480 nm laser was employed to pump the erbium-doped fiber. The light was reflected by a linearly chirped fiber Bragg grating, and the output was amplified by two times. The output is 1.41 mW with a bandwidth of 10 nm. The working current corresponding to the linear output is from 375 mA to 645 mA.
