There is described a semiconductor microcrystallite doped glass that exhibits SHG, and a method of preparing, or encoding, a semiconductor microcrystallite doped glass by the simultaneous injection of fundamental and second harmonic fields, such as 1.06 .mu.m and 532 nm. More specifically, the disclosure...http://www.google.es/patents/US5253258?utm_source=gb-gplus-sharePatente US5253258 - Optically encoded phase matched second harmonic generation device and self frequency doubling laser material using semiconductor microcrystallite doped glasses
