Abstract
A reflective optical system () comprising at least one reflective aspheric surface () of focal length fand optical axis (Z), the surface being configured so that an incident laser beam () propagating along an axis (Z') is focused along the optical axis (Z) with a FWHM ((Full Width at Half Maximum) of the intensity of the reflected beam along the optical axis (Z) being larger, preferably by a factor of at least 10, than the FWHM of the intensity of a focused beam reflected by a parabola having same focal length fand same optical axis (Z), receiving same beam.
