A simple analytical formula is derived for the output quality parameter in terms of the input beam width, refractive index of the axicon material and the angle of the axicon wedge.journal articlehttp://dx.doi.org/10.1016/0030-4018(94)90397-2http://www.sciencedirect.com/metadata only access535LawsÓptica (Física)2209.19 Óptica Física
