ABSTRACT:
A laser mirror mounting arrangement for a laser formed within a laser body is shown. The mounting arrangement includes a mounting base mounted upon the laser body. A stem is attached to the mounting base to which, in turn, the laser mirror is mounted. The stem has a coefficient of thermal expansion selected to maintain the mirror in a fixed position. This is accomplished by permitting the stem to expand due to thermal expansion in one direction, while the laser body expands due to thermal expansion in the opposite direction.
