How strong is a purple laser?

The strength of a purple laser, which typically emits light in the range of 400 to 450 nanometers, can vary based on its power output, measured in milliwatts (mW). Common consumer purple lasers range from 1 mW to 5 mW, which are generally safe for use. However, higher-powered purple lasers, exceeding 5 mW, can pose risks and should be handled with caution. The perceived brightness and potential hazards also depend on the specific wavelength and power level.
