摘要

High quality La_2CaBioO_19 single crystals doped with Pr~(3+) ions were grown by means of the top seeded solution growth method. The concentration of Pr3"1" ions in the starting melt was equal to 4 at%, which, due to small distribution coefficient, in consequence gave single crystals containing 2.5 at% of Pr~(3+) ions. The piezoelectric coefficients were measured for the pure and Pr~(+3) doped crystals. The principal changes under influence of the nanosecond pulsed 1064 nm Nd:YAG laser were observed for the LCBO nanocrystallites incorporated into the polymer matrices. The introduction of the Pr~(3+) ions favors enhanced piezoelectric constants. In turn the nanocrystallites with enhanced piezoelectricity lead to the enhanced laser threshold damage.
