Abstract
Potassium lithium niobate (K3Li2−xNb5+x O15+2x: KLN) has been expected as a hopeful material for SHG blue laser because of its excellent features such as a large nonlinear coefficients, high optical damage resistance, and wide noncritical phase-matching characteristics at room temperature.1,2 Applying rnicro-pulling-down (μ-FD) method to crystal growth of KLN overcame the cracks and compositional fluctuations difficulties.3 We have studied SHG properties of μ-PD-grown KLN single crystals both along and perpendicular to the growth axis.
