Abstract
UNDER laser radiation separately located disk-shaped cracks are formed in irradiated transparent dielectrics such as polymethylmethacrylate (PMMA), polystyrene (PS) and polycarbonate (PC). To explain this for materials with small absorption coefficients the sample must have particular sorts of microdefects and we now consider the size, location, structure and properties of these microdefects.
