Paper Abstract

It is believed that the light emission induced by laser pulse gives some information on the damage initiation mechanics of fused silica. The laser induced fluorescence (LIF) of high purity fused silica irradiated by KrF laser is studied experimentally. LIF bands centered at 650nm of fused silica fused with surplus H2 atmosphere was observed simultaneously with CCD and spectrometer in the cross direction of laser beam. Significant blue-shift of LIF is observed with the irradiation intensity increasing before laser induced breakdown. The technique to improve the signal intensity of LIF and the signal/noise ratio are discussed.
