A method is described for growing inclusion-free crystals of KTP using <0 1 0> seed orientation. The top seeded solution growth technique is employed, along with a high rotation rate for the seed crystal, using a five-zone resistive-heating furnace. A minimum wastage of the seed is achieved by maintaining the seed-liquid interface by surface tension forces. Elements fabricated from KTP crystals under Type II phase matching for second-harmonic generation from Nd:YAG radiation exhibited a conversion efficiency exceeding 60% (without anti-reflection coating).
