Abstract: The work is devoted to the peculiarities of conducting calibration procedures for thermoelectric detectors via setting a pulsed laser load. Thermoelectric detectors and their sensitive elements based on Cr and GeTe crystallites were studied. A laser diode with a radiation power of up to 30 watts was used as a radiation source. A high-speed photodiode was used to assess the overall sensitivity of the sensor. The aspects of performing calibration procedures described in the work make it possible to obtain volt-watt characteristics for various sensitive elements and determine the degree of reliability of the values of heat fluxes produced by them when used in a pulsed gas dynamic experiment.

Keywords: thermoelectric detector, thermal emf, pulsed laser diode, photodiode, calibration.
