Your question triggered me reading a bit around, verifying that my statement above is still true. It certainly was with the 1.6 W laser, because the PWM pulses resolved into individual dots a higher laser movement speeds - see here. But I just learned that there are more sophisticated circuits which do “true” laser power control by finely controlling the current through the laser diodes and using optical feedback to ensure stable operation - if they use this in the 10 W laser, 0.5% may really mean 50 mW constant output power, and then it would be safe to look on that dot. I guess when I’ve a bit more time at my hands, I may look a bit deeper.
