Can a Class 1 laser remove hair? I was faced with this question when I found an old hair removal laser in a thrift shop. It is labeled as class 1 the safest of all laser classes.
Being sceptical, I bought the laser and will in this video test its wavelength on a spectrometer and its power on a laser power meter.
Can you guess how strong it is? And is it a safe class 1?
