Dark Marking Capability of 20W Fiber Laser on Aluminum

Описание к видео Dark Marking Capability of 20W Fiber Laser on Aluminum

The result is that a speed of less than 500 mm/s and a power greater than 40% seems to produce the darkest mark. All marking was done at 25khz one pass (crosshatch).

I did test a few marks with text after this grid to see if there was much difference by varying the frequency from 20, 25, 30, and 50 khz but it was nowhere near as severe as changing the speed and power.
