Laser Laser A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. The term "laser" originated as an acronym for "light amplification by stimulated emission of radiation". The first laser was built in 1960 by Theodore H. Maiman at Hughes Research Laboratories, based on theoretical work by Charles Hard Townes and Arthur Leonard Schawlow. A laser differs from other sources of light in that it emits light "coherently". Spatial coherence allows a laser to be focused to a tight spot, enabling applications such as laser cutting and lithography. Spatial
Dazer Laser statement that "the threats vision is temporarily impaired, their balance is effected, and they become affected by nausea", calling the weapon a "puke-ray" and "chunder-beam". By the end of 2010, LEI's website said that "in some cases, a feeling of nausea may occur, however the Dazer Laser® is not intended to make you sick." 2008 - Laser Energetics completes its research and begins the physical engineering of its Dazer Laser." 2009 - Laser Energetics announces its nonlethal laser weapon. 2010 - Results from for the eye safety study proves the Dazer Laser can be operated safely.
