Abstract

An all-fiber supercontinuum laser source with a piece of highly nonlinear fiber inserted into a mode-locked fiber laser is experimentally demonstrated. This laser achieves mode-locking based on the Mamyshev mechanism and realizes supercontinuum generation spanning from 1330 nm to 2030 nm directly. Mode-locking based on the Mamyshev mechanism can be obtained easily, and the influence of the parameters of the laser cavity on the supercontinuum laser source is investigated. This supercontinuum laser source has a simple structure, and no amplifier stages are required. It demonstrates intracavity supercontinuum generation in mode-locked fiber laser based on the Mamyshev mechanism and exploits its operation further.
