Title
(EN) MARKING METHOD OF FIBER LASER MARKER
(FR) PROCEDE DE MARQUAGE D'UN MARQUEUR LASER A FIBRE
Abstract
(EN)
Provided is a marking method of a fiber laser marker, the fiber laser marker including an optical pump outputting an optical signal to a resonator, and a Galvano scanner scanning at a predetermined location with a laser beam emitted from the resonator. The marking method includes: measuring a delay time for which the output of the laser beam is delayed, the delay time depending on a jump time between when the optical signal is output to the resonator and when the laser beam is emitted from the resonator; moving a mirror of the Galvano scanner to a starting point of a next marking; calculating the jump time for which the mirror of the Galvano scanner is moved to the starting point of the next marking; calculating the delay time depending on the jump time; driving the optical pump to apply the optical signal to the resonator, and making the mirror of the Galvano scanner stand by for the delay time; and driving the mirror of the Galvano scanner and performing the marking.

Cette invention concerne un procédé de marquage d'un marqueur laser à fibre. Le marqueur laser à fibre décrit dans cette invention comprend une pompe optique qui produit un signal optique vers un résonateur, et un galvano-scanneur conçu pour balayer, à un emplacement prédéterminé, un faisceau laser émis par le résonateur. Le procédé de marquage décrit dans cette invention consiste: à mesurer un décalage durant lequel la sortie du faisceau laser est retardée, le décalage dépendant d'un moment de saut entre le moment où le signal optique est produit vers le résonateur et le moment où le faisceau laser est émis par le résonateur; à déplacer un miroir du galvano-scanneur vers un point de départ d'un marquage suivant; à calculer le moment de saut auquel le miroir du galvano-scanneur est déplacé vers le point de départ du marquage suivant; à calculer le décalage en fonction du moment de saut; à commander la pompe optique afin qu'elle applique le signal optique au résonateur, et à mettre le miroir du galvano-scanneur en attente durant le décalage; puis à commander le miroir du galvano-scanneur et à exécuter le marquage.
