I have a dumb question if you get close to my 3.4W 445 while burning at a distance of let's say 24"-48" I can hear an audible extremely high pitched squeal when I get the focus to its narrowest point where it is at its most powerful burning beam.
What is this? If you move the beam to a fresh spot it stops momentarily then begins again. I have noticed this same thing with my 1W 520nm, and also my 538mW 405nm.
Just curious how the focus/surface the laser hits can affect the driver. It's almost like you start to hear it the second the laser begins to burn and break the surface its aimed at.
