Laser-Induced Point Defects in Fused Silica Irradiated by UV Laser in Vacuum
Figure 2
Absorption spectra of fused silica preirradiated in vacuum by different laser pulses numbers (10, 50, 100, 200, and 1000); the pulse fluence is 8.16 J/cm2. The sample exhibits a broad absorption between 500 nm and 700 nm.
