摘要：

Permanent photobleaching of blue luminescence with a maximum at similar to 390 nm in Ge-doped fiber preforms by exposure to the third harmonic (354 nm) of a Nd:YAG laser has been observed. The experimental results show that photodestruction of a germanium oxygen-deficient center can occur without photoionization. (C) 1996 Optical Society of America
