Abstract

Abstract

Great nonlinear coefficients of quasi-phase-matching crystals may be used in optical parametric chirped-pulse amplification (OPCPA) system. This is particularly true for the applications that require high repetition rates and small pump energies. The numerical simulations show that a saturatiom amplificatiom gain of above 6.2×106 and over 25% pump-to-signal conversion efficiency can be obtained with a periodically poled crystal in the first stage of the optical parametric amplification. A high repetition rate and sub-terawatt OPCPA laser system with diode-laser pumping was discussed．
- optical parametric chirped pulse amplification,
- quasi-phase-matching,
- high repetition rate
