The article reports on the direct pumping of an optical-parametric-amplifier with a femtosecond oscillator which provides relatively high-energy pulses in the near-infrared at a repetition rate of 1 megahertz. The work is part of a European Union-funded collaboration that started as an effort toward micromachining of optical guides. A standard saturable absorber mirror and chirped mirrors was used by the oscillator to provide passive modelocking.

    The ultra-broadband phase matching was experimentally observed in a DKDP crystal upon parametric amplification of signal radiation with a wavelength of 911 nm in a pump field with a wavelength of 527 nm. The original scheme was used to excite the first parametric amplification stage by chirped...

    In experiments on the parametrical amplification of femtosecond pulses in wide-aperture DKDP crystals, a power of more than 100 TW has been reached, which is much higher than the record level achieved in such lasers. The energy efficiency obtained for the parametric amplifier is equal to 27%....
