Abstract: A laser for emitting simultaneously a first and second laser lights having respectively first and second wavelength differing from each other. The laser comprises: an optical resonator defining a first optical path and a second optical path, the first laser light travelling along the first optical path and the second laser light travelling along the second optical path; a modulated gain element inserted in the optical resonator for amplifying the first and second laser lights as the first and second laser lights propagate in the optical resonator respectively along the first and second optical paths, the modulated gain element having a variable gain modulated with a modulation period, round trip times of the first and second laser lights along respectively the first and second optical paths being respective integer multiples of the modulation period; and an output port for releasing the first and second laser lights from the optical resonator.
