Simulation results for the Type I degenerate OPCPA pumped at 1.054 μm. (a) Efficiency evolution along the crystal length in LGN (red curve) and LiNbO₃ (blue curve). (b) Temporal profiles of the input pump or chirped signal pulses, the residual pump pulses, and the amplified chirped signal pulses in LGN and LiNbO₃. (c) Spectra of the input signal and the amplified signals in LGN and LiNbO₃. The red and blue dashed curves represent the OPP produced in LGN- and LiNbO₃-based OPCPAs, respectively. (d) The compressed pulses without and with OPP compensation in LGN- and LiNbO₃-based OPCPAs. The dashed curves represent the corresponding Fourier-transform-limited pulses.
