Dual Wedge Fine GDD and CEP Tuning Application Set-up

The Mounted Wedges Setup is a precision optical system designed for fine dispersion and Carrier Envelope Phase (CEP) tuning in ultrafast laser applications. Using ultrathin glass wedge pairs with broadband antireflection coatings, this setup enables continuous group delay dispersion (GDD) control over a wide dynamic range. Available in two wedge angles and sizes, the system integrates seamlessly into standard optical mounts for compact and stable alignment.

The use of two optical wedges that are aligned at Brewster’s angle allow for manipulation of a beam’s optical path length, while minimizing light losses induced from the angular deviation of the beam. Translating the prism setup can allow for precise tuning of positive GDD, as a function of wedge insertion. Using this setup in conjugation with a pair of prisms or chirped mirrors can allow for precise compensation of GDD, compressing pulses while maximizing the output intensity.
