| Abstract: | Simulation and experimental results for high repetition rate all-normal dispersion Yb:fiber ring lasers are demonstrated for the cavity dispersion from 0.01 to 0.025 ps 2 .The simulation shows that the pulse spectrum has the potential to reach>30 nm for the dispersion of 0.014 ps 2 under practical pump power. This potential is proved by the experiment.Maximum spectral width of 30 nm is achieved at the repetition rate of 285 MHz under the 850-mW pump power.Average output power is 550 mW and dechirped pulse is 78 fs. |
