RT Journal Article T1 Quality changes of gaussian beams propagating through axicons A1 Piquero Sanz, Gemma María A1 Mejías Arias, Pedro Miguel A1 Martínez Herrero, Rosario AB The beam quality parameter of gaussian fields propagating through axicons is investigated. 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.
