I have this Chinese 473nm laser. It's supposed to be rated at 100mw (roughly). I have a new Coherent lasercheck as well with it's NIST documentation. When I measure the output at 473nm it says 66mw. When I change the line to 445nm it says 116mw.
My questions are:
Is the line coming out of the LBO crystal REALLY 445nm?
Or is the laser just a dud because it's not outputting 100mw @ 473nm? OR, is my lasercheck out of calibration?
What do you think?
