Summary: | A laser source (2) is used in a geodesic device (1) to improve the emission of laser light, in which the laser diodes (2b) emitting multimodal radiation ar e influenced by a mode-selective component (2d) such that the laser radiation emitted by the laser source (2) has monomodal character. An edge emitter (2b ) or a vertical semiconductor emitter with an external cavity, is hence used, in which a mode selective component (2d) is arranged, for example, a monomode fibre or resonator mirror, which has the effect of a mode-selective resonato r construction. Components with negative dispersion can be used for pulse compression to compensate for the greater pulse duration generated by the lengthened cavity. |
