Abstract:
A method of attaching and sealing at least one mirror to a ring laser gyro block, the ring laser gyro block and the at least one mirror comprising a ring laser gyro block assembly, the method comprising, in order, the following steps:positioning the at least one mirror so that a mounting surface of the at least one mirror is substantially parallel to a mounting surface of the ring laser gyro block; establishing a wicking gap of between about 0.0001 inches and 0.015 inches between the mounting surface of the at least one mirror and the mounting surface of the ring laser gyro block; applying an aqueous sodium silicate solution to the wicking gap, wherein the aqueous sodium silicate solution wicks into the wicking gap; hardening the aqueous sodium silicate solution by exposing it to infrared light; and allowing the aqueous sodium silicate solution to cure farther by baking the ring laser gyro block assembly.
