A multi-stage optical parametric (OP) module configured with an upstream optical parametric amplification (OPA) stage, a plurality of intermediate OPA stages, and an output OPA stage arranged along a single optical path and with The pump beam, signal beam and IR beam interact at the respective λp, λ3 and λf wavelengths. The OPA stages are each provided with time delay compensation (TDC) components that alternate with the OPA stages along a single optical path. The TDC components are each configured to compensate for the group velocity mismatch between the pump and signal beams, and to guide the IR, pump, and signal beams along the optical path between the OPA stages, while preventing the idler beam from Propagation after subsequent parameter interactions. |
