Features of controlled laser thermal cleavage of crystal quartz

Controlled laser thermal cleavage of crystalline quartz has been simulated. The thermoelastic fields formed in a square single-crystal quartz plate as a result of successive laser heating and exposure to coolant have been calculated for five different versions specified by the crystal cut orientation and direction of laser beam displacement. The results have been verified experimentally using a CO2 laser. The simulation results can be used in the electronics industry to optimize laser cutting of quartz crystals.
