Abstract[English]
In accordance with an aspect of the invention, an apparatus (1) for emitting electromagnetic radiation is provided. The apparatus comprises a gain element (4), an optical arrangement defining a resonator and arranged to re-direct radiation emitted by the gain element (4) along a beam path back onto the gain element (4), the optical arrangement comprising an output coupler (5) configured to couple a portion of the radiation in the resonator out of the resonator, and a pump arrangement configured to pump the gain element. The optical arrangement further comprises a passive device (10), for example a biprism, placed in the resonator in the beam path, the passive device having at least two surface portions (11, 12) at an angle to each other. The passive device (10) is arranged to direct first radiation portions (31) and second radiation portions (32) of the radiation, which first and second radiation portions (31, 32) are incident on different ones of the surface portions (11, 12), to be spatially separated. The apparatus is for example suitable as a source of dual-comb pulsed laser radiation.[French]
Un aspect de l'invention concerne un appareil (1) pour émettre un rayonnement électromagnétique. L'appareil comprend un élément de gain (4), un agencement optique définissant un résonateur et agencé pour rediriger le rayonnement émis par l'élément de gain (4) le long d'un trajet de faisceau en retour sur l'élément de gain (4), l'agencement optique comprenant un coupleur de sortie (5) configuré pour coupler une partie du rayonnement dans le résonateur hors du résonateur, et un agencement de pompe configuré pour pomper l'élément de gain. L'agencement optique comprend en outre un dispositif passif (10), par exemple un biprisme, placé dans le résonateur dans le trajet de faisceau, le dispositif passif ayant au moins deux parties de surface (11, 12) faisant un angle entre elles. Le dispositif passif (10) est agencé pour diriger des premières parties de rayonnement (31) et des secondes parties de rayonnement (32) du rayonnement, lesdites premières et secondes parties de rayonnement (31, 32) étant incidentes sur différentes parties de surface (11, 12) parmi les parties de surface (11, 12), pour être séparées spatialement. L'appareil est par exemple approprié en tant que source de rayonnement laser pulsé à double peigne.
