Growth rate of microscopic cracks in alkali-halide crystals irradiated by pulses from a CO2 laser
Abstract
Microscopic cracks form in the interior of alkali-halide crystals if the crystals are irradiated by CO2 laser pulses of power density exceeding a critical value. The cracks increase in size and concentration within the caustic of the focusing lens as the laser power is increased. The rate of crack formation was determined photographically by using illuminating light pulses synchronized with the CO2 laser pulses.
