Popis:	A conception of using laser-driven resonator cavity switches with an active element of semiconductor to measure the semiconductor's loss tangent being unknown is proposed and discussed. A sample calculation for an existent gallium arsenide-based prototype for the frequencies around 300 GHz has demonstrated an unambiguous determination of the loss tangent in the range of at least four orders and two methods. Such a redundancy helps to come over a fabrication imprecision for each prototype and ensure high precision of measurements.
