High-repetition rate optical parametric chirped pulse amplification system for attosecond science experiments

A high power, high repetition rate optical parametric chirped pulse amplification (OPCPA) system is presented. The OPCPA delivers Carrier-Envelope Phase (CEP)-stable 7 fs pulses, with up to 0.19mJ of energy, with a total compressed average power of 19 W. The system is being currently integrated in an attosecond pumpprobe beamline capable of combining attosecond pulses in the extreme ultraviolet (XUV) with synchronized few-cycle pulses in the near infrared (NIR). The main motivation for this development is to perform pump-probe experiments with attosecond time resolution, in which electrons and ions produced during photo-ionization are detected in coincidence utilizing a reaction microscope.
