GENERATOR AND LASER SYSTEM COMPRISING COUPLED SUB-CAVITIES

摘要

The invention relates to a laser system comprising a cavity (1) formed by at least two sub-cavities (2, 3), and means (4) for optically pumping a first (2) of said at least two sub-cavities (2, 3). In said system, the optical pumping means (4) are arranged in such a way as to not reach the laser emission threshold of the first sub-cavity (2), said first sub-cavity (2) comprising means (21) for generating a short impulse, and a second sub-cavity (3) comprising external triggering means (30). The first and second sub-cavities (2, 3) are coupled such that the triggering of the second sub-cavity causes the release of the short impulse generated by the first sub-cavity (2). The invention also relates to a laser generator comprising at least two such laser systems (1a, 1b), to a light emission system with a wide spectral band, comprising such a laser system and means (31) for generating non-linear optical effects inserted into the second sub-cavity (3), and to a light generator with a wide spectral band, comprising such a laser generator having at least one laser system provided with means (31) for generating non-linear optical effects inserted into the second sub-cavity (3).
