Generator and laser system comprising coupled sub-cavities

摘要

A laser system having a cavity formed by at least two sub-cavities and a mechanism for optically pumping a first of the at least two sub-cavities. In the system, the optical pumping mechanism is arranged in such away to not reach a laser emission threshold of the first sub-cavity, the first sub-cavity (2) comprising a device for generating a short pulse, a second sub-cavity (3) comprising an external triggering device. The first and second sub-cavities are coupled such that the triggering of the second sub-cavity has at least two such laser systems, to a light emission system with a wide spectral band, comprising such a laser system and a mechanism for generating non-linear optical effects inserted into the second sub-cavity, and to a light generator with a wide spectral band, comprising such a laser generator having at least one laser system provided with a mechanism for generating non-linear optical effects inserted into the second sub-cavity.

1. A laser system comprising a cavity formed of two sub-cavities and means for optically pumping a first sub-cavity of said at least two sub-cavities, said optical pumping means are arranged so as not to reach a laser emission threshold of the first sub-cavity, said first sub-cavity including means for generating a short pulse, said means for generating a short pulse comprises a gain medium and a saturable absorber, a second sub-cavity of said at least two sub-cavities including external triggering means, and said first and second sub-cavities are interferometrically coupled, such that active triggering of said second sub-cavity causes the release of a short pulse generated by said first sub-cavity.
