Laser damage in ferrites of MnZn spinels and other possible interactions
MetadataShow full item record
Pulsed laser damage of ferrites of MnZn spinels was studied. Some of the samples were treated by nuclear gamma radiation and LY particles and then exposed to laser beams in different working conditions. The sample and damage quality was evaluated on the basis of X-ray, optical and SEM microscopy and micro-hardness experiments. The characteristic brittleness after nuclear gamma irradiation of ferrites and other materials was confirmed in the cases of interactions with laser beams. Characteristic cases of material cracks with CO2 laser were found. (C) 1997 Elsevier Science Ltd.
