Abstract
In an apparatus for manipulating laser beams with mirrors, the beam is caused to emerge substantially in alignment with the initial direction of the incoming beam by deflecting the incoming beam with a first mirror whose position is selectively adjustable to a second mirror which preferably has a parabolic surface, and then from the second mirror the beam is directed to a third, flat mirror whose position is also adjustable so that the beam is focussed on the region to be treated in a position substantially in alignment with the initial direction of propagation. An improved system for supplying screening gas to the region under treatment is also disclosed.
