MARKING METHOD OF FIBER LASER MARKER

摘要

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.
