Discrete bisoliton fiber laser [PDF]

open access: yesScientific Reports, 2016
AbstractDissipative solitons, which result from the intricate balance between dispersion and nonlinearity as well as gain and loss, are of the fundamental scientific interest and numerous important applications. Here, we report a fiber laser that generates bisoliton – two consecutive dissipative solitons that preserve a fixed separation between them ...

Theory of cw Raman oscillation in optical fibers [PDF]

open access: yes, 1979
A theory for Raman fiber laser oscillators is presented. The Stokes output and the residual pump power are shown to be calculable from a knowledge of the input pump power and the fiber characteristics. The evolution of the pump and the Stokes waves along
