Abstract[English]
A pulsed laser diode driver includes a refresh circuit configured to generate a refresh current using a received input voltage. A current amplitude of the refresh current is controlled by the refresh circuit based on a voltage level of a source voltage received by the refresh circuit. A source capacitor of the pulsed laser diode driver is configured to receive the refresh current and to develop the source voltage therefrom. An inductor of the pulsed laser diode driver has a first terminal that is directly electrically connected to the source capacitor. One or more switches of the pulsed laser diode driver are configured to control a current flow through the inductor to produce a high-current pulse through a laser diode that corresponds to a peak current of a resonant waveform developed at an anode of the laser diode.[French]
Un circuit d'attaque de diode laser pulsée comporte un circuit de rafraîchissement configuré pour générer un courant de rafraîchissement au moyen d'une tension d'entrée reçue. Une amplitude de courant du courant de rafraîchissement est commandée par le circuit de rafraîchissement sur la base d'un niveau de tension d'une tension de source reçue par le circuit de rafraîchissement. Un condensateur source du circuit d'attaque de diode laser pulsée est configuré pour recevoir le courant de rafraîchissement et pour développer la tension source à partir de ce dernier. Un inducteur du circuit d'attaque de diode laser pulsée présente une première borne qui est directement connectée électriquement au condensateur source. Un ou plusieurs commutateurs du circuit d'attaque de diode laser pulsée sont configurés pour commander un flux de courant à travers l'inducteur pour produire une impulsion de courant élevé à travers une diode laser qui correspond à un courant de crête d'une forme d'onde résonante développée au niveau d'une anode de la diode laser.
