The crystal isolation system of the present invention protects a laser crystal from environmental factors such as humidity and dust. A crystal is placed in a housing which has two ports in it, and flexible tubes are placed in each port. Cap pieces cover the ends of the tubes and prevent deleterious environmental factors such as dust and moisture from entering the isolation system while allowing laser light to enter the system. A desiccator attached to the system removes moisture from the air inside the system, and an led and detector apparatus are is used to help indicate the remaining useful life of the desiccant in the desiccator.

Crystal isolation housing

A mirror mount assembly has a base plate positioned at one end of a laser resonator, and a movable plate spaced from and positioned substantially parallel to the base plate. One or more elastic springs are connected between the base plate and the moveable plate to provide tip and tilt of the movable plate and translation of the moveable plate away from or towards the base plate. The elastic springs include a bushing made of an elastic material, and at least three elastic dimples formed in the bushing circumferentially in a plane across a bushing longitudinal axis. Further, the elastic spring has a bushing made of an elastic material capable of elastic expansion and contraction. The bushing includes a threaded interior side and a longitudinal axis from a first open end of the bushing to a second open end of the bushing. At least three elastic dimples are formed in the bushing circumferentially in a plane across the bushing longitudinal axis and extend into the bushing threaded interior side to flexibly contact one or more threads of a screw received in the bushing threaded interior. The dimples permit rotation of the bushing and screw relative to each other to advance and retract the screw along the longitudinal axis, and provide a selected and maintainable adjustment of the screw along the bushing's longitudinal axis with reduced mechanical hysteresis of the screw.
