Title:
LASER PULSE POWER CONTROL METHOD, PULSE OPTICAL FIBER LASER DEVICE, AND LASER CUTTING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/214200
Kind Code:
A1
Abstract:
A laser pulse power control method, a pulse optical fiber laser device (3), and a laser cutting system. Said method comprises: acquiring an analog input signal and receiving a laser control pulse signal (S101); detecting the laser control pulse signal, and when any one laser control pulse is detected, switching a laser device to a laser output state, also acquiring an analog value of the analog input signal in a continuous time period of the laser control pulse, and obtaining, according to the analog value, the magnitude of working current driven by laser light (S102); generating a control signal on the basis of the working current, so as to enable the laser device to output, according to the magnitude of the working current, a laser pulse having a corresponding power in the continuous time period (S103). The pulse optical fiber laser device (3) and the laser cutting system are used to execute the laser pulse power control method. According to the present invention, the laser pulse power is controlled by means of the analog input signal and the laser control pulse signal which are continuously inputted, such that a control interface (50) is simpler, the control efficiency is higher, and synchronous control can be realized.
