The development of femtosecond all-solid-state diode-pumped high power laser systems operating with a high repetition rate is possible due to the rapid growth of technology of new Yb-doped materials. The basic principles, features, and amplification scheme of femtosecond pulses to subterawatt level and element base for laser ceramic and crystalline materials, doped with ytterbium ions (Yb:Y2O3, Yb:KYW etc.) and nonlinear LBO optical crystals, are developed. The design of cryogenic terawatt diode-pumped femtosecond laser system at repetition rate up to 1000 Hz and hybrid (parametric and laser) method of chirped pulse amplification with the optical synchronization of the radiation of the pump and amplification channels is discussed. The initial cascade of developed cryogenic hybrid diode-pumped laser system consisted of cryogenic Yb:Y2O3 ceramic (100 MHz, 160-180 fs) master oscillator, stretcher, diode pumped regenerative amplifier and compressor is experimentally investigated.
