ABSTRACT:
Laser apparatus having a pair of concave end mirrors facing each other through a laser gain medium. The end mirrors are mounted so as to permit tilting thereof. One of the end mirrors has a center of curvature situated between the end mirrors at a distance from the other end mirror of up to one-eighth of the distance between the end mirrors through the laser gain medium. The other end mirror has a center of curvature situated between the end mirrors at a distance from each of the end mirrors of at least three-eighth of the distance between the end mirrors through the laser gain medium. In practice, this substantially reduces the sensitivity of the laser apparatus and laser action to end mirror tilting and to bending of the laser gain medium or of a tube containing same. It also substantially increases the alignment tolerance and adjustability of the end mirrors and other parts of the laser structure and permits potting of gas lasers.
