Hello guys,
I recently bougth this cheap 445nm laser (~50$) for a laser cutter project:
https://www.ebay.fr/itm/Focusable-2...e=STRK:MEBIDX:IT&_trksid=p2060353.m2749.l2649
It is really inexpensive, and I'm a bit suspicious about its power. I'm new to the laser world, and I don't have good comparison figures to detect if it is a real 2.5W laser.
I was expecting to be able to cut 3mm of soft wood, but when I tested, even after 30s focused on the same point, I only had a 2mm hole, whereas I watched video of guys with 2.5w 445nm lasers cutting this kind of wood with few passes at 1mm/s.
I measured the current consumed by the driver : at 12V it eats 0.6 amps. It seems low for me, I was expecting around 2A, but still, I'm not sure if this value is ok for a 2.5W 445nm laser.
What do you think guys. Is it a real 2.5W laser according to your experience with other laser of this type?
Thank you for your help!
