Query: Dynamics of dissipative solitons in a high repetition rate
  normal-dispersion erbium-doped fiber laser   The dynamics of dissipative solitons (DSs) are explored in a high repetition
rate normal-dispersion erbium-doped fiber laser for the first time. Despite of
the high fundamental repetition rate of 129 MHz and thus the low pulse energy,
a DS train with a dechirped pulse width of 418 fs, period-doubling of single
and dual DSs, as well as 258 MHz 2nd-order harmonic mode-locking of DSs can be
observed in the fiber laser with increasing pump power and appropriate
settings. A transmitted semiconductor saturable absorber and a wavelength
division multiplexer/isolator/tap hybrid module are employed to simplify the
laser configuration, thus not only increasing the repetition rate, but also
enhancing the stability and robustness of the fiber laser due to the commercial
availability of all the components.
