Abstract

An optical system for a laser comprises at least means for imaging a laser beam onto a first optical material (1, 1b). These imaging means comprise at least one optical image system (2) for focusing said laser beam onto the first optical material (1, 1b) and at least one optical means for changing the angle of the propagation axis of the laser beam, whereby the optical imaging system is positioned between the optical means and the first optical material, and may be described by formula (I) whereby D is substantially zero
