To nowadays, there is great current interest in the use of high-power, ultrashort
pulse lasers for a wide range of applications such as the generation of short x-ray pulses,
the generation of high-order harmonics, the generation of plasma beams, the acceleration
of atomic particles, the processing of materials, etc. A major breakthrough in a field of the
generation of powerful lasers was connected with development of optical parametric
chirped pulse amplification (OPCPA). This technique provides a wide amplification
bandwidth and in principle an essentially constant coefficient of amplification, thus
allowing the output power to be increased by two orders of magnitude and compact high
power laser systems to be developed [1]. Now the peak powers of the OPCPA laser systems
exceed the traditional lasers with chirped pulse amplification (CPA)
