Ql. Zhao et Ys. Huang, GROWTH ZONE BOUNDARY IN A SELF-FREQUENCY DOUBLING CRYSTAL OF ND3-DOPED YAL3(BO3)4(), Chinese Physics Letters, 10(6), 1993, pp. 362-364
One of the main defects in the self-frequency doubling crystal of Nd3-doped YAl3(BO3)4 (NYAB), which may be the key factor to influence the
crystal performance, is the growth zone boundary that has been identi
fied by means of x-ray diffraction topography. The characteristic boun
dary is formed usually by the basal plane and the pyramidal planes or
by the pyramidal planes themselves.
