The generation of broadband photosource in fiber amplifier with different seed lasers - soliton and dissipative soliton pulse

Soliton and dissipative soliton have different pulse width, pulse energy, and propagation behaviors. The results are quite different for the generation of broadband photosource. In this work, broadband photosource with a wide spectral range based on two pulsed seed lasers is investigated. A high flatness spectrum with a bandwidth greater than 300 nm and predicted spectrum up to 2000 nm covering Er and Tm emission regime has been obtained by amplifying soliton pulsed laser. 370-mW higher average power broadband photosource has been obtained based on the amplification of dissipative soliton lasers. The proposed broadband photosource does not need to add further nonlinear medium in case of introducing unnecessary losses. These results pave the way for the realization of broadband, high flatness spectrum, compact light sources, and the use of all-fiber optic structure to lay the foundation for integration and detection applications, etc. © 2022 Elsevier Ltd
