Abstract

The invention relates to a laser controller for simultaneously controlling pulse width and frequency, which mainly solves the problem of different technical parameters of different lasers in the prior art, especially different trigger signals required by different lasers. The laser energy and frequency triggered by different lasers are also different. At the same time, the problem of different laser parameters required for laser cutting of materials of different materials is solved. The present invention adopts an adjustable laser controller, adjusts the frequency and pulse width of the signal output from the laser controller to the laser according to different lasers to ensure the quality of laser cutting, better solves the above problems, and can be widely used in laser processing equipment.

Description

technical field [0001] The invention relates to a laser controller which simultaneously controls pulse width and frequency. Background technique [0002] Lasers are commonly used in a variety of industrial operations, including inspection, machining, and cutting of metals such as thin steel sheets. Due to the simple process and fast speed, laser cutting has the characteristics of small slit width, good incision parallelism, small surface roughness, high dimensional accuracy, small workpiece deformation and heat-affected zone, no mechanical stress and surface damage, etc., and can accurately cut shapes Complex micro-parts. Different laser frequencies and pulse widths will inevitably produce different cutting effects when cutting materials of the same material. That is to say, the frequency and pulse width of the laser seriously affect the quality of the cut material surface. Therefore, during laser cutting, the frequency and pulse width of the laser must be suitable and the...
