Journal ArticleDOI
Self-similar propagation and amplification of parabolic pulses in optical fibers.
TL;DR: Self-similarity analysis of the nonlinear Schrödinger equation with gain results in an exact asymptotic solution corresponding to a linearly chirped parabolic pulse which propagates self-similarly subject to simple scaling rules.
Journal ArticleDOI
Exact self-similar solutions of the generalized nonlinear Schrödinger equation with distributed coefficients.
TL;DR: A broad class of exact self-similar solutions to the nonlinear Schrödinger equation (NLSE) with distributed dispersion, nonlinearity, and gain or loss has been found and the stability of these solutions has been confirmed by numerical simulations of the NLSE.
Journal ArticleDOI
Self-similar propagation of parabolic pulses in normal-dispersion fiber amplifiers
TL;DR: In this article, a self-similarity analysis of high-gain optical fiber amplifiers with normal group-velocity dispersion has been performed for the parabolic pulse propagation.
Journal ArticleDOI
Self-similar propagation of high-power parabolic pulses in optical fiber amplifiers
TL;DR: The self-similar scaling of the propagating pulse in the amplifier is found to be determined by the functional form of the gain profile, and the solution in the high-power limit that corresponds to a linearly chirped parabolic pulse is found.
Journal ArticleDOI
Mode-locked femtosecond all-normal all-PM Yb-doped fiber laser using a nonlinear amplifying loop mirror.
TL;DR: A robust laser design employing all normal dispersion polarisation maintaining fibres operating at 1 μm, mode-locked using a nonlinear amplifying fibre loop mirror that provides an additional degree of freedom allowing easy control over the pulse parameters.
