Transient optical absorption properties in visible region of K9 glass under nanosecond ultraviolet (UV) laser irradiation (355 nm, 10 Hz) are investigated and discussed. Both the transient absorption spectra and absorption decay properties are presented in this paper. Transient absorption spectrum of K9 glass under UV laser irradiation shows a broad absorption band with maximum at 450 nm and a shoulder at 600 nm. The observed transient absorption bands in K9 glass are suggested to arise from laser induced defects identified as boron oxygen hole centers (BOHC) and non-bridge oxygen hole centers (NBOHC), respectively. Pump-fluence dependency of transient absorption intensity indicates that nonlinear absorption of the pump laser plays an important role in generating such UV-induced hole centers..
