Transmission Bragg-grating Grisms for pulse compression

Bragg transmission gratings made of ion-etched fused silica with diffraction efficiencies outmatching surface relief gratings over ultrawide bandwidths are commercially available and provide an elegant alternative to reflective gratings. In this paper, the authors demonstrate that combined to high index prisms, highly efficient, dispersive and compact grism pulse compressors can be designed to compensate for both the group delay dispersion (GDD) and third order dispersion (TOD) of bulk materials.
