We derive a dissipative soliton area theorem that contrasts with other area theorems: the energy scales directly with the pulse duration, and the energy has an upper bound. Predictions are verified in a fiber oscillator.
A dissipative-soliton oscillator can replace the oscillator, stretcher, pulse-picker, and pre-amplifier in a chirped-pulse fiber amplifier. 150-ps pulses at 3-MHz repetition rate are amplified to 1-muJ energy with pulse duration as short as 670 fs.
Fiber lasers operating in the normal dispersion regime with a filter are analyzed with simulations of coupled-field equations. This model predicts new operating modes previously unrecognized by scalar simulations.
A new modelocking regime governed by the Ginzburg-Landau equation is demonstrated in an anomalous dispersion fiber laser. Output pulses are long, flat-topped, and highly-down-chirped, with energies above 150 nJ and repetition rates below 300 kHz.
Femtosecond pulse generation by spectral filtering of a chirped pulse is demonstrated at 1550 nm. An erbium fiber laser with large normal dispersion and a spectral filter generates 200-fs and 1-nJ pulses.
Fiber lasers modelocked by filtering of a chirped pulse are analyzed with the Ginzburg-Landau equation. A range of experimental pulse shapes are predicted remarkably well by an exact analytical solution, and constitute dissipative temporal solitons.
The behavior and performance of femtosecond fiber lasers without any anomalous dispersion in the cavity is presented. Experimental results agree with numerical simulations. 8-nJ and 210-fs pulses are generated, and significant performance improvements are expected.
