100-TW femtosecond laser based on parametric amplification
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 ...

New scheme of a petawatt laser based on nondegenerate parametric amplification of chirped pulses in DKDP crystals
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 o...

Ionization spectrum transformation and compression of powerful femtosecond laser pulses in experiments on the propagation in gas-filled dielectric capillaries
The propagation of an intense (I≤106 W/cm2) femtosecond laser radiation with a duration of ∼100 fs through gas-filled dielectric capillaries was studied. The radiation with a power up to 0.2 TW propagates along t...
