Abstract

CsLiB₆O₁₀ (CLBO) is a highly promising nonlinear optical material. However, its application is limited due to the difficulties in producing optically uniform CLBO crystals. High viscosity of Cs₂O-Li₂O-B₂O₃ melt retards both natural and forced convection in the melt. With the goal to improve the heat and mass transfer in the melt, the study of crystallization in the Cs₂O-Li₂O- B₂O₃-MoO₃ system was carried out. The CLBO crystals 60 X 40 X 20 mm in size grown using LiCsMoO₄ as a solvent were found to be free of cracks, bubbles, and inclusions. Nonlinear optical parameters and physical properties of those crystals turned out to be similar to those reported before. Mohs' hardness is 5.5, transparency window ranges from 0.18 to 2.7 micrometers , nonlinear coefficient is 1 pm/V, angular and spectral bandwidth of synchronism are 0.5 mrad-m and 0.1 nm-cm. The walk-off angle is 2 degree(s) at 0.53 micrometers . The nonlinear optical elements for the 4^th harmonic of Nd:YAG laser were fabricated and tested.
