ABSTRACT:
A stress-free optic element or window for use in equipment such as lasers. In this window a plurality of circular or curved grooves are formed in the window surface to prevent stresses from reaching the central region of the window used for light beam transmission. The plurality of grooves effectively form a resilient or spring like zone between the periphery of the window and the central region so that stresses generated in the peripheral mounting area are isolated from reaching the central stress-free area.
