Abstract
We emulate the general guidelines for the design of a 100-terawatt-level optical parametric chirped pulse amplifier (OPCPA) system operating at 2.2 m. A two-stage OPCPA system based on a crystal is numerically calculated with a split-step Fourier transform algorithm. The maximization of both conversion efficiency and bandwidth are analyzed. The tolerance of time jitter and pump intensity fluctuation are considered in the OPCPA system. The theoretical scheme based on the OPCPA present in this paper paves the way for building a 100-TW-level mid-infrared laser system.
