2.The focusing curves ( r z ), which higher order mode laser beams(i.e.: the mode TEM 11 、TEM 12 (or TEM 21 )、TEM 22 of Hermitian Gauss beams and the mode TEM 10 、TEM 11 of Laguerre Gauss beams) propagate through a focusing optical system (for example: a pair of lens focusing system), are obtainable on the basis of Huygens Fresnel principle and Sampling theory and by programming , calculating, and making use of Graftool.
7.The Propagation of Wigner Distribution Function Through a Pair of Cylindrical Lenses System
8.Basing on conventional 4 elements 70° field of view wide angle Zeiss eyepiece,we have designed two hybrid refractive diffractive eyepieces by replacing the doublet of the eyepiece with hybrid refractive diffractive singlet.
