LASER - Light Amplification by Stimulated Emission of Radiation

The DEWs are still technically lasers but VISIBLE light is but a fraction of the electromagnetic spectrum.

A better term would actually be ERASER - Electromagnetic Radiation Amplification by Stimulated Emission of Radiation. Microwaves, gamma rays, X-rays, etc. are all part of the electromagnetic spectrum as is visible light.
