Laser Dazzlers at work

The US department of defense is working on their new Laser dazzler that will be used to stop the drivers without making any injuries to them. Previously the Green laser developed for this purpose has been sent to Iraq and Afghanistan US forces, but they are harmful at short ranges and guess what it leads to damage of eyes for no of US troops and civilians during their ‘friendly fire’ incidents. Therefore the US Department of Defense’s Joint Non-Lethal Weapons Directorate is developing a pulsed laser uniquely designed to stop drivers without injuring the eyes even at short range. The wavelength of this laser in proportion to the light absorbed by vehicle windscreen thus it vaporize the outer layer of glass and produce plasma. This plasma will absorb the remaining pulse and reemits it as brilliant white light hence it won’t produce any harm to the eyes. Regardless of vehicles distance from laser, the light is emitted from windscreen therefore the effect on driver’s eye also will be same.
