Peak visibility for the human eye is 555nm, which is why red lasers trend towards the top of that scale, while newer blue and violet pointers land in the high 400s. Power output is measured in milliwatts (mW), . Laser Power Meters are ideal for measuring the energy output of laser beams for testing or laser system applications at Edmund Optics. Laser Measurement products are used to measure or characterize laser beams.
Presently lasers that are powerful enough to machine metal are large and heavy and require lots of power and cooling water to operate thus are not useful as portable death rays.
Q: How is laser power measured ?
A: Laser power is measured in watts - the same watts used to measure the power of light bulbs.
The highest measured power output was 66. Laser pointer power is measured in milliwatts, which is denoted with mW in laser pointer descriptions. The mW rating measures the output of power from the laser.
