Title:
MULTI-STAGE OPTICAL PARAMETRIC MODULE AND PICOSECOND PULSED LASER SOURCE INCORPORATING THE MODULE
Document Type and Number:
WIPO Patent Application WO/2020/160116
Kind Code:
A8
Abstract:
A multi-stage optical parametric (OP) module is configured with upstream, multiple intermediate and output optical parametric amplification (OPA) stages arranged along a single light path and interacting with pump, signal and IR light beams at respective λρ, λ3 and λf wavelengths. The OPA stages each are provided with a time delay compensation (TDC) assembly alternating with the OPA stages along the single light path. The TDCs assemblies each are configured to compensate for the group velocity mismatch between pump and signal beams and guide the IR, pump and signal beams along the light path between the OPA stages while preventing propagation of an idler beam after each subsequent parametric interaction.
