In the experimental setup, the pulse of a Nd:YAG glass laser (1060-nm wavelength, 3-nsec pulse duration, output energy up to 1 J) generated damage at the surface and in the bulk of optical glasses. The slightly focused beam exhibited a 2-mm diam in the sample plane with a peak energy density of up to 50 J/cm(2). The surface damage was investigated on 5-mm thick samples with a differential interference microscope (Nomar-ski). In most cases, the damage was small pits probably caused by absorption… CONTINUE READING
