The LMA-EDFA suppresses nonlinear soliton-self-frequency-shift effect happened during femtosecond pulse amplification, in which the fiber laser pulse is reshaped to a low-pedestal hyperbolic-second shape with nearly 100% energy confinement. The pre-chirped amplification from 0.96 to 104 mW and the simultaneous compression of a passively mode-locked fiber laser pulse from 300 to 56 fs is demonstrated. The input pulse energy of 24 pJ is amplified up to 2.6 nJ with shortened pulsewidth of 56 fs and peak power as high as 46 kW. © 2007 Optical Society of America.Amplification; Doping (additives); Image compression; Laser pulses; Solitons; Ultrashort pulses; Fiber laser pulses; Nonlinear solitons; Pulse amplification; Pulsewidth; Fiber amplifiersjournal article10.1364/OE.15.0029932-s2.0-33947427097
