Název v původním jazyce

Broadband femtosecond OPCPA system driven by the single-shot narrow-band iodine photodissociation laser SOFIA

Popis výsledku v původním jazyce

A two-stage optical parametric amplifier driven by a frequency-tripled beam of the iodine laser system SOFIA was built. This single-shot OPCPA facility and the system synchronizing the pump and signal pulses are described. The chirped seed pulse of a Ti:sapphire oscillator at the 800 nm central wavelength is amplified in an LBO and a KDP amplifier over 10^8 times. The amplified spectral bandwidth of 68 nm corresponds to the transform-limited pulse duration of 14 fs. This implies a compressed pulse of TWpower. Gain measurements reveal a good match with the theoretical predictions. Signal and idler beam fluence profiles are presented. The suitability of the iodine photodissociation laser as a pump source for the OPCPA technique is thus proved for the first time experimentally. A distinctive feature of the iodine laser is its narrow gain bandwidth (< 0.1 cm-1) and, therefore, the conventional Chirped-Pulse Amplification technique does not lead to pulse durations at the femtosecond level.
