An Off-Axis, Single-Pass, Radial-Group-Delay Compensator Design Using an Offner Triplet for a Broadband OPCPA Laser

摘要

An off-axis, single-pass, radial-group-delay compensator was designed using an Offner triplet and two negative lenses for a broadband (810~1010-nm) optical parametric amplifier laser. It reduces radial group delay from 270 fs to 0.7 fs.
