Ys. Lee et al., Effect of Neodymium : Yttrium aluminum garnet laser irradiation on crystallization in Li2O-Al2O3-SiO2 glass, J AM CERAM, 84(10), 2001, pp. 2433-2435
A 355-nm neodymium:yttrium aluminum garnet laser, produced by a harmonic ge
nerator, was used for the nucleation process in photosensitive glass contai
ning Ag+ and Ce3+ ions. The pulse width and frequency of the laser were 8 n
s and 10 Hz, respectively. Heat treatment was conducted at 570 degreesC for
1 h, following laser irradiation, to produce crystalline growth, after whi
ch a LiAlSi3O8 crystal phase appeared in the laser-irradiated Li2O-Al2O3-Si
O2 glass. The present study compares the effect of laser-induced nucleation
on glass crystallization with that of spontaneous nucleation by heat treat
ment.
