Japan, Feb. 24 -- FURUKAWA ELECTRIC CO LTD:THE has got intellectual property rights for 'WAVELENGTH VARIABLE LASER DEVICE AND CONTROL METHOD OF THE WAVELENGTH VARIABLE LASER DEVICE.' Other related details are as follows:
Application Number: JP,2022-018159
Category (FI): H01S5/0625
Stage: PROBLEM TO BE SOLVED: To provide a wavelength variable laser device and a control method of the wavelength variable laser device, in which a stability of a frequency of a laser beam output when continuously changing the frequency in a wide band is high.SOLUTION: In a wavelength variable laser device continuously sweeping a frequency of a laser beam output to an external part, a control part continuously sweeps the frequency of the laser beam while outputting the laser beam to the external part while oscillating a first wavelength variable laser element, sets the number of laser oscillation frequency of a second wavelength variable laser element to a first frequency during the sweeping to oscillate the laser, and an output of the laser beam to the external part is disconnected in order to be a stand-by state. In the case where it is determined that the frequency of the laser beam of the first wavelength variable laser element is appropriately matched to the first frequency, the output to the external part of the laser beam of the first wavelength variable laser element is disconnected, and the stand-by state of the second wavelength variable laser element is cancelled to output the laser beam of the second wavelength variable laser element to the external part as at least one step.SELECTED DRAWING: Figure 1 (Grant)
