摘要

Samples of crown glass, fused silica, Perspex and Irtran 1 were irradiated with 0.2-microsec duration pulses from a CO2 laser, at energy densities of between 10 and 800 kJ/sq m. The damage induced was thermal in origin and was controlled more by the absorption depth in the material than by thermal diffusion. The major damage mechanisms were cracking and flaking in the case of crown glass, and vaporisation in the cases of fused silica and Perspex. Irtran 1 was the most difficult to damage because of its comparatively large absorption depth. Impulse production was studied, and was explained by simple models involving vaporisation and the excitation of laser-supported waves. (Author)
