We demonstrate single-pass and double-pass pre-chip managed (PCMA) rod-type fiber amplifier systems, in which pulse pre-chirping and compression is realized using Gires–Tournois interferometric (GTI) mirror pairs. Such a combination of GTI mirrors and PCMA allowed to achieve compact, easy to adjust, high slope (up to 65%) and optical (up to 73%) efficiency amplifiers that produce broadband pedestal-free nearly transform-limited (TL) 75 fs–85 fs pulses with average power of ∼ 20 W at 76 MHz repetition rate. These nearly TL pulses can only be obtained at optimal pre-chirping group delay dispersion values. Laser sources with the aforementioned parameters can be used as a high power and pulse quality laser systems for nonlinear optics experiments.
