Bragg thickness criterion for intracavity diffraction gratings

Abstract

The grating thickness limit lFP between the Raman-Nath and the Bragg diffraction regimes is calculated for an index grating placed in an asymmetric Fabry-Perot resonator with a totally reflecting back mirror and compared with that which was obtained for the same grating with no cavity lM . Owing to the increase of the effective interaction length inside the Fabry-Perot cavity, the stronger the front mirror reflectivity R1 of the cavity, the smaller the thickness above which the whole diffracted intensity can be concentrated into one unique diffracted beam: lFP=[(1−√R1)/(1+√R1)]lM/2.
