YAl sub(3)(BO sub(3)) sub(4): Crystal growth and characterization

The growth and characterization of YAl sub(3)(BO sub(3)) sub(4) (YAB), a potential nonlinear optical crystal for the fourth harmonic generation of Nd:YAG laser, was reported. Using top-seeded solution growth method, a YAB crystal with the dimensions of 16x16x18 mm super(3) was obtained from B sub(2)...

Description
Summary:The growth and characterization of YAl sub(3)(BO sub(3)) sub(4) (YAB), a potential nonlinear optical crystal for the fourth harmonic generation of Nd:YAG laser, was reported. Using top-seeded solution growth method, a YAB crystal with the dimensions of 16x16x18 mm super(3) was obtained from B sub(2)O sub(3)-Li sub(2)O flux system. The advantages of this flux system and the growth process were discussed in detail. The as-grown YAB crystal was verified by powder X-ray diffraction. The transparency spectra indicated that the cut-off edge of the as-grown YAB was 170 nm. The fourth harmonic generation of a frequency doubled Nd:YAG laser, from 532 to 266 nm, was carried out with a YAB crystal doubler for the first time. Output pulse power obtained was 2.4 mW at 266 nm and the conversion efficiency from 532 to 266 nm was about 15.6%.
