Abstract

Phosphorus-doped fiber has great advantages in supercontinuum (SC) generation because it can narrow the gap between Raman-related peaks and valleys owing to its special Raman gain. In this paper, a random fiber laser (RFL) structure and a main oscillator power amplifier (MOPA) structure are used to pump a self-made phosphorus-doped fiber. The results show that the output spectrum of the latter structure is more favorable in spectral flatness improvement. The 15 dB bandwidth covers from 690 nm to 2320 nm and the output power is 15.1 W. In the range of 1076 -2010 nm, the spectral intensity fluctuates within 3 dB. To the best of our knowledge, the spectral range and flatness are the best among SC generation based on phosphorus-doped fiber methods, which provide a solution for improving the spectral characteristics of the SC

由掺磷光纤产生平面超连续谱

掺磷光纤由于其特殊的拉曼增益，可以缩小拉曼相关峰谷之间的差距，在超连续谱（SC）的产生中具有很大的优势。本文采用随机光纤激光器（RFL）结构和主振功率放大器（MOPA）结构泵浦自制掺磷光纤。结果表明，后一种结构的输出光谱更有利于提高光谱平整度。15db带宽覆盖690nm ~ 2320nm，输出功率为15.1 W。在1076 ~ 2010 nm范围内，光谱强度波动在3db以内。据我们所知，基于掺磷光纤的SC生成方法的光谱范围和平直度是最好的，这为改善SC的光谱特性提供了一种解决方案
