The 0.3-PW short pulse solid-state laser system was developed and investigated
in University of Michigan. The world record laser intensity of 2⋅10²² Watt/cm²
and the temporal contrast of the record value 1015 were reached. Several new
methods for solving bottleneck problems of the CPA lasers were suggested and
implemented during the laser construction. Most of them will be presented in
this report, among them:
•       The method for increasing extracted energy from multipass amplifiers.
Method was successfully applied in the other laboratories and allowed to
achieve the  record output power 2 PW .
•       New optical system for improvement of temporal contrast up to the
record value of 1011.
•       New method for the alignment of the Petawatt compressor with    10-6
rad accuracy.
•       First demonstrated the compression of 30 TW laser pulses from 30 down
to 14 fs via spectral broadening by self-phase modulation.
