Composition for growing laser crystals
摘要:
A composition for growing a laser crystal is represented by the formula of Li �R.sub.n .alpha..sub.1-n! �(Ga.sub.p In.sub.q) .beta..sub.1-p-q ! F.sub.6+n where n is within a range from 10.sup.-5 to 0.1, each of p and q is within a range from 0 to 0.6, a total of p and q is within a range from 0.001 to 0.6, .alpha. is at least one member selected from the group consisting of Ca, Sr, Ba and Na, .beta. is at least one member selected from the group consisting of Al, Cr, Ni, Co and Fe, and R is a rare-earth element. The composition enables the distribution coefficient of rare-earth element to get closer to 1 and thus enables the laser crystal to have a high and uniform concentration of rare-earth element and to have a large size.
