Abstract

Basically new induced polar dielectric media with controlled polarization properties and possessing unique physical characteristics as compared with the true pyroelectrics are advanced for IR optoelectronics.On the base of these effective pyroactive structures a new class of pyroelectric sensor for measurements of intense and super-intense laser fluxes for the spectral range from visible to middle IR is proposed. The first type sensors - multifunctional pyroelectric converters, the second type - pyroelectric transmission-type power sensors. Because it is impossible to get a high transmission of the true pyroelectrics due to the spontaneous electric moment, sensors of the second type are the devices operating on the tertiary pyroelectric effect, that has been registered in non-pyroelectrics, too.
