Abstract

In this contribution, we report the generation of high energy, high temporal quality, ultrashort pulses from a single stage double-pass short length Ytterbium-doped rod type fibre chirped pulse amplification setup. The fibre used as gain medium is a 95-cm long rod type microstructured fibre with a 80 μm core diameter and 200 μm pump cladding diameter. The fiber amplifier is seeded by 3 nJ pulses stretched to 550 ps at a pulse repetition rate of 100 kHz. We demonstrate amplification and compression up to 200 μJ energy in 240 fs with good temporal quality leading to ~ 750 MW peak power.
