This could be handy

The US government has unveiled a "non-lethal" laser rifle designed to dazzle enemy personnel without causing them permanent harm. But the device will require close scrutiny to ensure compliance with a United Nations protocol on blinding laser weapons.
The US Department of Defense (DoD) believes the weapon could be used, for example, to temporarily blind suspects who drive through a roadblock. However, the DoD has yet to reveal details of how the laser works.
The PHaSR may attempt to address safety concerns by automatically sensing its distance from a target. The limited information released by the DoD includes mention of an "eye-safe range finder", which may mean the laser's power is adjusted depending on the distance to the target. The system is also said to incorporate a "two wavelength laser system", which may be designed to counter goggles that can filter out certain wavelengths of laser light.
