THE BASIC PRINCIPLES OF BIBO CRYSTAL

Hygroscopic crystal elements deteriorate when they're not constantly held in sufficiently dry air (or simply a dry purge gasoline). This is applicable e.g. to KDP and BBO, As well as in a lesser extent to LBO. It can be useful to maintain such a crystal in a to some degree elevated temperature, which makes it simpler to retain it dry.Kingwin Optics
