High average power ultrafast fiber amplifiers

We report one three non-linear strategies implemented to generate high quality pulses in several pulse duration and energy regimes. The amplification of ultrashort pulses using spectral compression and non-ideal parabolic amplification techniques will be review. Furthermore, the use of a novel architecture of non-linear fiber chirped pulse amplifier delivering high temporal quality 100 µJ, 300 kHz, 340 MW pulses will be described.
