Why does my green laser turn red?

What you are seeing is leakage of the 808nm laser diode output that in better constructed units would have been blocked by an IR bandstop or green bandpass filter. When the output of the laser is reflected or diffracted, the various wavelengths are split up allowing the near red to be separated from the dominant green.

Is Blue laser illegal?
