Nd:YCOB

Nd-doped YCOB (Nd:YCa₄O(BO₃)₃) is a nonlinear optical crystal, which is commonly used as an active laser medium. It can be grown from a melt by the Czochralski technique. It belongs to the monoclinic system with space group C_s²-Cm. Each neodymium ion replaces a yttrium ion in the YCOB crystal structure.
