Аннотация:We study parametric down-conversion (PDC) of optical
laser radiation in the strongly frequency non-degenerate
regime which is promising for the generation of quantum-
correlated pairs of extremely different spectral ranges, the
optical and the terahertz (THz) ones. The possibility to
detect tenuous THz-frequency photon fluxes generated
under low-gain spontaneous PDC is demonstrated using
a hot electron bolometer. Then experimental dependences
of the THz radiation power on the detection angle and on
the pump intensity are analyzed.
