Abstract
Fiber-based chirped-pulse amplification (CPA) at 1 µm wavelength can be realized using standard single-mode fiber and a subsequent grating compressor. With this setup, the second-order dispersion β2 can be fully compensated for by the compressor. An immanent disadvantage of this scheme is that third-order dispersion (TOD) β3 of the fiber and the grating compressor are usually cumulative as both are positive in sign. Therefore, a fiber stretcher not only has the advantages of a waveguide device. It also causes longer minimum pulse durations after compression due to TOD compared to the use of a grating stretcher, unless a more complicated compressor setup with gratings and prisms is used.
