Abstract:
The second-harmonic generation (SHG) properties of a potassium lithium niobate (KLN) crystal with the size of 8×20×43 mm 3 were studied in detail. The KLN crystal was grown from a melt consisting of 32 mol% K 2 O, 24 mol% Li 2 O and 44 mol% Nb 2 O 5 (denoted as the melt 32:24:44) by the top-seeded solution growth (TSSG) method. The ferroelectricity of the KLN crystal was revealed by the marked dielectric anomaly at the Curie temperature. The full-widths at half maximum (FWHMs) of the wavelength- and temperature-tuning curves of a 4-mm-long KLN crystal sample were found to be 0.6 nm and 2°C, respectively. The SHG conversion efficiency of this crystal was studied and estimated to be 0.03%/W for an input power of 748 mW. The CW tunable blue laser covering the range of 431.1–437.6 nm was achieved by tuning the crystal temperature in the range of 24–80°C. The crystal studied in this paper is more inhomogeneous and has lower SHG efficiency than the KLN crystal grown from the melt 31:26:43, which has higher Li 2 O content.
