Claim 0:
1. A wavelength-tunable multi-beam light source comprising:
a first laser for emitting light at a first optical frequency;
a plurality of second lasers for emitting light at different second optical frequencies; and
an optical frequency mixer coupled to the first laser and to the plurality of second lasers for nonlinear optical mixing of optical frequencies of the light emitted by the first laser and the light emitted by each one of the plurality of second lasers, to provide a plurality of output light beams at mixed optical frequencies;
wherein at least one of the first laser or the plurality of second lasers is tunable in optical frequency, whereby each output light beam of the plurality of output light beams is wavelength-tunable.
