Scaling of dissipative soliton fiber lasers to megawatt peak powers by use of large-area photonic crystal fiber
Optics letters, 2010•opg.optica.org
We report an all-normal dispersion femtosecond laser based on large-mode-area Yb-doped
photonic crystal fiber. Self-starting mode-locked pulses are obtained with an average power
of 12? W at 84? MHz repetition rate, corresponding to 140? nJ of chirped pulse energy.
These are dechirped to a near transform-limited duration of 115? fs. Experimental results are
consistent with numerical simulations of dissipative soliton intra-cavity pulse evolution, and
demonstrate scaling of 100? fs pulses to megawatt peak powers.
