Abstract

We report on the top seeded solution growth of LBO from an excess of B₂O₃ solution. Parameters investigated included the Li₂O/B₂O₃ ratio, rotation, pulling and cooling rates. Unstable crystal growth encountered, such as hopper growth and inclusions, can be attributed to the high viscosity of the solution, and methods of increasing the forced convection was examined by the melt simulation using the tracer method. With careful control of the above parameters, clear crystals of approximately 40 X 48 X 30 mm have been successfully grown. It was characterized that the grown LBO crystals have good optical homogeneity, no growth striations, no growth sector boundaries, small change of refractive index less than 1 X 10^-5/cm. A bulk laser damage threshold of LBO was determined to be 45.0 GW/cm² at 1.064 micrometers , 1.1 nsec pulse width. This is one of the highest bulk damage threshold of any inorganic nonlinear optical crystal.
