摘要
A chirped pulse fiber amplifier with nonlinear compensation, includes elements for generating a light pulse having an initial peak-power P0 and an initial duration T, a stretcher including at least one optical diffraction network having a line density higher than 1200 lines/mm and suitable for time-stretching the pulse and of inserting a time asymmetry in the stretched pulse, an amplifying fiber including a doped optical fiber section coupled with an optical pumping element and suitable for amplifying the stretched pulse for producing a pulse having a power, a compressor with optical diffraction grating suitable for time-compressing the amplified pulse so that the stretcher and the compressor are mismatched, the mismatch between the stretcher and the compressor being suitable for simultaneously compensating the second- and third-order nonlinear dispersions in the amplifying fiber during the propagation of a pulse having an initial power P0 through the chirped pulse amplifier.
