High-energy picosecond single-pass multi-stage optical parametric generator and amplifier
文献摘要：
We demonstrate a new management of multi-stage optical parametric generator (OPG) and amplifier (OPA) to obtain high-energy picosecond sources with high beam quality.The setup of multi-stage OPG-OPA requires mode-matching between the pump beam and the stable mode of the OPG-OPA.In a proof-of-principle experiment,the single-pass multi-stage OPG-OPA consists of three walk-off compensated KTP crystal pairs and two lenses,pumped by an 86 ps,1064 nm 10 kHz picosecond laser.The signal light at ～ 1.77 μm has an average output power of 502 mW with record energy up to 50.2 μJ.The beam quality factor of the signal light can be improved to Mx2 × My2 =1.87 × 2.16 after filtering out about 40％ signal power.To the best of our knowledge,it is the first picosecond single-pass multi-stage OPG-OPA pumped at kHz regime.
