Description

Détails

Ultrashort pulse back-reflection task requires group delay management. Due to this reason common retroreflector prism is not applicable as it introduces considerable group delay dispersion which distorts pulse’s temporal shape. Hollow configuration of right angle retroreflector, consists of two HR coated mirrors, featuring total reflectance higher than 99,6 %. Moreover, group delay dispersion (GDD) of HR coatings is optimized to be <20 fs², what makes HR right angle retroreflector a perfect solution for fs applications.
