AI Technical Summary

Problems solved by technology

The MOPA laser controls the pulse width through the serial communication protocol. Since the serial communication protocol must be controlled in sequence, the control efficiency is low, so it takes a long time to switch pulses.

Abstract

The embodiment of the invention provides a pulse width modulation method and device, an MOPA laser and a readable storage medium, and relates to the field of laser processing. After receiving a pulse signal of the laser marking card, the MOPA laser calculates the current signal period and the current signal pulse width of the pulse signal according to the pulse signal, then converts the current signal period into the current signal frequency, and obtains a frequency comparison result by comparing the current signal frequency with the maximum signal frequency. And finally, the current signal pulse width is adjusted according to the frequency comparison result. According to the invention, the current signal period of the MOPA laser is converted into the current signal frequency, the current signal frequency is compared with the maximum signal frequency, and then the pulse width is adjusted, so that compared with the prior art that the pulse width is switched through a serial port communication protocol, the time required for switching the pulse is greatly shortened, and the conversion efficiency is improved.

Description

technical field [0001] The present application relates to the field of laser processing, in particular to a pulse width modulation method, device, MOPA laser and readable storage medium. Background technique [0002] Laser processing technology is a technology that uses the characteristics of the interaction between laser beams and substances to cut, weld, drill and micro-process metals or non-metals. It has been widely used in various fields such as automobiles, electronics, and machinery manufacturing. With the continuous development of laser processing technology, the requirements for lasers, one of the core components of laser processing equipment, are getting higher and higher. [0003] MOPA (Master Oscillator Power-Amplifier) ​​is a master oscillator power amplifier, which amplifies the high-quality seed light source generated by the master oscillator with high power. In the application of MOPA lasers, due to the need to face different processing materials and adapt t...
