LASER CAVITIES TERMINATED BY DIFFRACTION GRATINGS.

Abstract

A theoretical study is performed of the resonant modes of a laser cavity having end mirrors with periodic reflectivity. A particular example is examined in which the end mirrors are constituted by two identical strip diffraction gratings. The modes and the corresponding eigenvalues are evaluated in successive approximations. It was found that a particular frequency exists for which losses are very low, while neighboring frequencies suffer heavy losses. This effect increases very rapidly with the total number of strips in the grating. (Author)
