摘要：
KTP crystals have been grown by two nucleation techniques namely spontaneous nucleation in flux medium and nucleation on Pt rod using K6P4O13 flux.10 degrees C/h, 7 degrees C/h, 0.8 degrees C/h, 0.4 degrees C/h and 0.2 degrees C/h cooling rates were applied for spontaneous nucleation and crystals up to 15 x 7 x 4 mm(3) in size were grown. 1 degrees C/h and 0.8 degrees C/h cooling rates were also used for nucleation on Pt rod and crystals up to 8 x 6 x 3 mm(3) in size were grown. The effect of cooling rate on size, morphology and optical quality of grown crystals by both techniques were studied. For nucleation on Pt rod upper and lower rotation rates limits and an optimum rotation rate were distinguished for each cooling rate. Quality of the grown crystals by both techniques was characterized by optical transmission analysis.
