AbstractAn optical system has been designed with spherical lenses to focus high power (~
kJ) , Nd-YAG laser (1.06)μm with 55mm beam diameter to spot size diameter
(1.248μm ). Minimum number and thin lenses were used in the design. The spot
diagram, the point spread function (PSF), and accumulated energy , were used as
parameters to qualify the performance of the system.
The results show the high quality of the system for laser diameter less 55mm and
the a spherical lenses are necessary for larger diameters.
