Title (EN) METHOD OF OPTIMIZING THE OPERATION POINTS OF LASERS AND MEANS FOR CARRYING OUT THE METHOD
(FR) PROCEDE POUR OPTIMISER LES POINTS D'APPLICATION DES LASERS ET SYSTEME POUR METTRE EN OEUVRE CE PROCEDE
Abstract: front page image
(EN)A method of optimising the operation point of a laser, comprising characterising the laser and controlling the different laser sections. The invention is characterized by controlling the different laser sections (1, 2, 3) by varying the current injected into respective sections; causing the laser (30) to be sensed with respect to discontinuities occurring at mode jumps in a signal from a detection device firmly connected to the laser; effecting the control of the different laser sections (1, 2, 3) by means of a control unit (31); delivering different control combinations and the signal delivered from the detection device to the control unit (31); causing the control unit to detect the mode plane of the laser (30); storing at least a part of a mode plane or several mode planes in a memory (32) belonging to the control unit (31); and causing the control unit (31) to control different laser sections (1, 2, 3) such that the laser will obtain the desired operation point.
(FR)L'invention concerne un procédé pour optimiser le point d'application d'un laser qui consiste à étalonner le laser et à commander les différentes parties du laser. L'invention consiste à commander les différentes parties (1, 2, 3) du laser en régulant le courant qui les alimente; à contrôler le laser (30) pour détecter les discontinuités qui ont lieu lors des sauts de mode dans un signal provenant d'un dispositif de détection solidarisé au laser; à commander les différentes parties du laser (1, 2, 3) au moyen d'une unité de commande (31); à fournir différentes combinaisons de commandes ainsi que le signal qui va du dispositif de détection jusqu'à l'unité de commande (31); à détecter au moyen de l'unité de commande le plan de mode du laser (30); à stocker au moins une partie du plan de mode ou plusieurs plans de mode dans une mémoire (32) faisant partie de l'unité de commande (31) et; à commander les différentes parties du laser (1, 2, 3) au moyen de l'unité de commande (31), et ce pour obtenir le point d'application désiré du laser.
