Abstract
Compared with the traditional slow evaporation solution technique to grow KAP crystals, we have improved a set of Rapid Growth Technology of Continuous Filtration System based on existing research conditions. KAP crystals were grown by program-controlled solution cooling method. A KAP crystal with a size of 220 mm × 170 mm × 45 mm and a weight of 1934.9 g was successfully grown, which is the largest KAP crystal reported so far. The optical studies such as transmittance, absorption coefficient, optical energy band gap, photoluminescence, and Z-scan of the crystal show that the crystal is more excellent than the traditional slow evaporation solution technique.
