Abstract
To provide operating supervision of the process there is a need of means of control with high temporal stability and resistance to radiation excess. Receivers based on the thermoelastic effect in crystalline quartz are designed for energy measurement of lasers in single impulse mode or for average power measurement in operation monitoring of industrial lasers. In the research we analyze work of the receiver at single impulse exposure. The heat storage time of the receiver is defined. Specifics of signal generation in receivers on thermoelastic effect at multiple impulse exposure are also analyzed. An algorithm for voltage calculation of the receiver with given parameters is developed. The modelling shows that generated signal growth in the detector exposed to an impulse consequence can influence the power measurement result and thus the ways to reduce the effect are proposed.
