Class Information
Number: 372/42
Name: Coherent light generators > Particular active media > Insulating crystal > Utilizing color centers
Description: Subject matter wherein color centers are formed within the crystal material which consist of displaced electrons that are trapped in regions of positive charge or of a "hole" or region of electron deficiency, which behaves like a "negative electron" or "positive hole", which can be trapped or localized in well-defined sites and which can impart color to the crystal material.
