Instantaneous frequency measurement of dissipative soliton resonant light pulses
Abstract: We measured the instantaneous frequency profile of two different dissipative soliton resonant (DSR) light pulses, the usual flat-top and less-common trapezoid-shaped. The DSR light pulses were provided by an ytterbiumdoped polarization-maintaining fiber ring passively mode-locked laser using the adequately selected amount of net-normal dispersion. We confirmed that the DSR light pulses have a (moderately) low linear chirp across the pulse, except at the edges, where the chirp changes exponentially. This unique instantaneous frequency behavior can be succinctly resumed by the following parameters: linear chirp slope and leading and trailing chirp lifetimes. As the pump power increases, the linear chirp slope decreases, whereas the leading and trailing chirp lifetimes do not show an appreciably change. The results are compared with previous theoretical works.

Summary: | Abstract: We measured the instantaneous frequency profile of two
different dissipative soliton resonant (DSR) light pulses,
the usual flat-top and less-common trapezoid-shaped.
The DSR light pulses were provided by an ytterbiumdoped polarization-maintaining fiber ring passively
mode-locked laser using the adequately selected amount
of net-normal dispersion. We confirmed that the DSR
light pulses have a (moderately) low linear chirp across
the pulse, except at the edges, where the chirp changes
exponentially. This unique instantaneous frequency
behavior can be succinctly resumed by the following
parameters: linear chirp slope and leading and trailing
chirp lifetimes. As the pump power increases, the linear
chirp slope decreases, whereas the leading and trailing
chirp lifetimes do not show an appreciably change. The
results are compared with previous theoretical works. |
