摘要：

A model is proposed for the process of laser-induced fracture in transparent dielectrics. The fracture occurs when mechanical stresses created in the crystal lattice by a spatially inhomogeneous cloud of nonequilibrium electrons exceed a threshold value. Relationships between of the mechanical stresses, the laser beam parameters and the crystal properties are established. Regions of the most probable primary crack formation are determined.
