Abstract A mount for a mirror of a laser resonator which will permit angular adjustment of the mirror with respect to two normal axes defining a plane at right angles to the axis of the laser resonator, while minimizing undesired mirror movement due to vibration and temperature variations. The mount, in the form of a flexure plate, is of unitary construction, comprised generally of a planar base plate member, two planar adjustment members, and connecting sections which couple the three planar members together. A first pair of the connecting sections rigidly link first and second oppositely disposed corner portions of the first adjustment member to the base plate member, and a second pair of the connecting sections rigidly link other oppositely disposed corner portions of the first adjustment member, generally disposed 90° relative to the first and second corner portions, to the second adjustment member. To achieve orientation of a mirror supported by the second adjustment member along one of the two normal axes, the corner portions of the first adjustment member lying intermediate the first pair of connecting sections are moved, such as by set screws or functionally equivalent devices, relative to the base plate member, and to achieve orientation of the mirror along the other of the two normal axes, the corner portions of the second adjustment member lying intermediate the second pair of connecting sections are moved relative to the base plate member.
A positioning apparatus of unitary construction comprising first, second and third generally planar members with the second member between the first and third members, a first pair of rigid connecting sections rigidly linking first and second oppositely disposed portions of a first of said planar members to a second of said planar members, a second pair of rigid connecting sections rigidly linking other oppositely disposed portions of said first of said planar members to a third of said planar members, and means for moving portions of one of said planar members relative to the other of said planar members and for moving other portions of said one of said planar members relative to only one of said planar members.
