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
