| Abstract: | Based on the theory of chirped p ulse parametric amplification, the application of optical parametric amplificati on in chirped pulse amplification is simulated. Gain and temporal characteristi c of optical parametric chirped pulse amplification is studied, especially in t he small signal condition and the large signal condition. The infection of the group velocity mismatch and the phase velocity mismatch in the process of the amplification are discussed respectively. The request of synchronization betwee n pump pulse and signal pulse is taked into account. The stability of the syst em is evaluated. |
