Abstract :
Summary form only given. Optical parametric chirped pulse amplification is a unique tool for amplification of ultra-broadband pulses to highest energies. In this this paper, we implement a stronger seed source which delivers muJ -level seed pulses with excellent temporal contrast. A 1 kHz, 1 mJ Ti:sapphire amplifier is used as front-end. The output pulses of the Ti:sapphire amplifier are broadened in a hollow-core fiber (HCF) obtaining ultra-broadband pulses with 400 muJ energy. A fraction of this output (50 muJ) is used to generate the seed for a broadband OPCPA in the near infrared.
