Abstract
The invention concerns an ultrahigh frequency emitting device, having:at least a first and a second microlaser (22, 24), emitting at two different frequencies &ohgr;1 and &ohgr;2,means of slaving the first and the second microlaser frequency-wise,an array of N elements (N≧2) (52, 54, 56, 58) placed on the path of the beam of the second laser, each element making it possible to impose a phase delay on the beam which passes through it,N means (26, 28, 30, 32) for mixing the beam emitted by the first laser and each of the N delayed beams, and for producing N signals of frequency &ohgr;1-&ohgr;2,N antenna-forming means (34, 36, 38, 40) for emitting radiation at the frequency &ohgr;1-&ohgr;2.
