  • Laser driving power source
    Patent number: 10938306
    Abstract: Response fluctuation of output current due to fluctuation of input voltage is reduced by control device (CM) including current fluctuation reduction control means (CFC) that is a regulator for regulating any of an output current command signal, a current detection value, and a control gain when the input voltage fluctuates.

  • LASER OSCILLATION DEVICE FOR DIRECT-DIODE LASER METHOD AND FAILURE DIAGNOSIS METHOD FOR LASER OSCILLATION DEVICE
    Publication number: 20210044081
    Abstract: A direct-diode laser oscillator 1 can emit laser light to a laser processing head 3 based on the driving commands received from a system controller 5, which can control a laser robot 4 including the laser processing head 3. The direct-diode laser oscillator 1 includes the following: laser modules 10 each including a plurality of laser diodes connected in series or in parallel; a power supply circuit 20 for driving the laser modules 10 at a constant current, and a power controller 30 for controlling the power supply circuit 20 based on the driving commands and performing a fault diagnosis of the laser oscillator 1 based on which one of a plurality of previously divided regions of a diagnosis map the current and voltage applied to the laser modules 10 belong to.
