Maiman operated the first functioning laser at Hughes Research Laboratories, Malibu, California, ahead of several research teams, including those of Townes, at Columbia University, Arthur Schawlow, at Bell Labs, and Gould, at the TRG (Technical Research Group) company. Maiman's functional laser used a solid-state flashlamp-pumped synthetic ruby crystal to produce red laser light, at 694 nanometers wavelength; however, the device only was capable of pulsed operation, because of its three-level pumping design scheme. Later that year,
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.
