BIBO

BIBO

BIBO crystals have broad transparent range ( from 286nm to 2500nm). Compared with other NLO crystals, BIBO has 4 times higher nonlinear coefficient than LBO and even 9 times larger effective SHG coefficient than KDP. It can be used in SHG and THG of high power Nd: lasers at 1342nm & 1319nm.
