NOT KNOWN FACTUAL STATEMENTS ABOUT BIBO CRYSTAL

Hygroscopic crystal products deteriorate when they are not generally kept in sufficiently dry air (or maybe a dry purge gas). This is applicable e.g. to KDP and BBO, and in a lesser extent to LBO. It can be practical to help keep this kind of crystal at a somewhat elevated temperature, which makes it easier to continue to keep it dry.Kingwin Optics
