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 seeded by 3 nJ pulses at 100 kHz of repetition rate. We demonstrate amplification and compression up to 200 μJ energy in 250 fs (assuming sech2 pulse shape) with good temporal quality leading to ~750 MW peak power.
