Abstract
A new type of the heavily-chirped solitary pulse
solutions of the nonlinear cubic-quintic complex Ginzburg-Landau
equation has been found. The methodology developed provides for a
systematic way to find the approximate but highly accurate
analytical solutions of this equation with the generalized
nonlinearities within the normal dispersion region. It is
demonstrated that these solitary pulses have the extra-broadened
parabolic-top or finger-like spectra and allow compressing with
more than hundredfold growth of the pulse peak power. The obtained
solutions explain the energy scalable regimes in the fiber and
solid-state oscillators operating within the normal dispersion
region and promising to achieve the micro-joules femtosecond
pulses at MHz repetition rates.
