Tested on the battlefield. Used by the U.S. military. It is the most compact laser device available for the purpose of target vision impairment from a distance.
Laser Dazzler™
A non-lethal weapon
The powerful 532nm (Green) Flashing Laser engages the target in a wall
of green laser light to disorient and distract the subject. This can
be a disorientation (temporary vision impairment) from a few seconds
to over a minute. It can overload the optic nerve rendering the target
nearly sightless for a period of time.
Specifications
Uses

The Laser Dazzler will inhibit directed action by temporarily blinding or interfering with sight. As a result, the military uses it (one of several uses) in Afghanistan and Iraq at checkpoints to keep (potential bombers) at a distance. It has also stopped many an errant civilian thereby saving them from being fired upon.
