Hermetic sealing of a nonlinear crystal for use in a laser system

A system for hermetically sealing a nonlinear optical (NLO) crystal for use in a laser system, comprising:

• an oven for receiving and baking a mounted NLO crystal, an enclosure base, a lid, and a plurality of window components, wherein the NLO crystal has been processed for frequency conversion;
• and
• an environmentally controlled chamber coupled with the oven and having a stage for receiving the mounted NLO crystal, enclosure base, lid, and plurality of window components from the oven after baking has resulted in a humidity level that is less than a predefined amount that will not damage the mounted NLO crystal, wherein the chamber includes a sealer tool for hermetically sealing the mounted NLO crystal into the enclosure base by sealing the lid and plurality of windows into openings of the enclosure base with the crystal being inside a cavity of the enclosure base;
• and
• a controller for causing, in cooperation with the oven and sealing tool, the following operations:
• baking the mounted NLO crystal, enclosure base, lid, and plurality of window components until the humidity level is less than the predefined amount, and
• after baking, hermetically sealing the mounted NLO crystal into the enclosure base by sealing the lid and plurality of window components into openings of the enclosure base to thereby form a crystal enclosure.
