High-power compact ultrafast pulse sources based on optical fiber lasers are discussed. The optical efficiency of fiber- based ultrafast pulse sources is optimized by the implementation of double-clad Yb-doped fibers. The spatial limitations of ultrafast single-mode fiber lasers and amplifiers are overcome by the implementation of diffraction-limited multi-mode rare-earth-doped fibers, allowing for the generation of ultrafast pulses with large peak powers. In the temporal domain, a further increase in obtainable peak powers is made possible by the use of chirped pulse amplification or the amplification of pulses with parabolic temporal profiles. Parabolic pulses are generated in the asymptotic limit in high gain fiber amplifiers operating in the positive dispersion regime.
