Abstract
A THz laser source includes a first generator suitable for emitting at least one first light emission and one second light emission of frequencies that are multiples of a first reference frequency; a second generator suitable for emitting at least one first light emission and one second light emission of frequencies that are multiples of a second reference frequency different from the first reference frequency; the THz laser source furthermore comprises a nonlinear crystal suitable for forming, from the first light emissions emitted by each of the first and second generators, a THz light emission generated by difference-frequency generation, of frequency comprised between 0.3 THz and 10 THz; and at least one first frequency-stabilizing module allowing the frequency of one of the second emissions emitted by one of the first and second generators to be stabilized to an atomic transition.
