LBO

€210.00 – €740.00

Lithium Tri-borate or LBO crystal is widely used broad optical transparency nonlinear optical material. Compared with other NLO crystals, such as KDP, LBO has 3 times larger conversion coefficient. It is suitable for  high power SHG applications because of minimal thermal lensing as compared to KTP.
