Abstract
In this paper, an improved top-seeded solution growth has been developed. Potassium titanyl phosphate (KTiOPO 4 or KTP) crystals with the size 60×60×50 mm 3 were grown from K 6P 4O 13 flux by this method, from the as-grown crystals big Z-cut crosssection (60×60 mm 2) could be attained, which would be advantageous to the electro-optical (E-O) applications of KTP crystals. The tests of E-O modulation by flux KTP has been realized, compared with LiNbO 3 and KD*P, the results showed that E-O modulator formed by flux KTP is free from acoustic ringing, and can modulate at subnanosecond level. All this indicated that KTP is an attractive material for various E-O applications, especially as an E-O Q-switch device in a high-repetition-rate, high-speed-traveling wave laser system.
