ABSTRACT:
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.
