The US military uses TALI - Threat Assessment Laser Illumination. TEMPORARY blinding lasers ( might ) be used overseas in Afghanistan and Iraq but not BLINDING lasers and I have not seen American police use them at all except on bomb robots and only the temporary flash blinding type. They are too risky for use in daily citizen interactions.
Laser designators and small arms aiming lasers are a different topic.
Temporary blinding lasers are usually green 515-532nm, there's also a puke ray that is multi color but not in use as far as I know. Maybe in Europe.
Temporary blinding lasers are designed to induce temporary flash blindness, but American police use Tasers and pepper spray because the NOHD varies from person to person and what is need to temporarily blind can also sometimes do lasting damage, it's too much of a liability, maybe for prisoner control, but not that I am aware of, kinetic bean bags and large rubber bullets, along with Tasers and pepper sprays are the non lethal tools of prison guards.
Now anti material lasers are as far as I know always invisible and the latest fiber type are in the 1050nm - 1250nm range and possibly over 1550nm so they ( the 1550nm and lower frequency/higher nm number ) are eye safe as far as powerful diffuse reflections until the point of physical destruction, but are retina safe as for diffuse reflections.
The permanently blinding lasers are not in the visible 400-800nm range, that would induce the blink reflex, they are in the 850-1400nm invisible range that still is focused by the eye's lens onto the retina and as far as I know only the Chinese military uses those. They are a violation of the Geneva convention and a war crime if used for human maiming/blinding but acceptable for anti material and range finding.
The early Abrams tank rangefinder used a flash lamp pumped crystal that could blind a soldier in an instant PERMANENTLY although that was not it's purpose, it was for range finding, but now they have switched to 1550nm and beyond to avoid blinding incidents and for tactical reasons.
--------INFO--------
The ELRF is a highly accurate, hardened system for the fire control sight in the Abrams Main Battle Tank. The ELRF gives the tank gunner the ability to determine target ranges in all battlefield conditions including fog, smoke, dust, sand and haze. Additionally, the rangefinder allows U.S. forces to train safely against each other.

THE ORIGINAL QUESTION YOU TOOK MY QUOATED ANSWER FROM WAS ABOUT USING A 445nm 1 Watt LASER AND THAT IS NOT USED BY MILITARY OR POLICE, NOT FOR TEMPORARY-IT WON'T WORK FOR THAT, and NOT FOR PERMENANT AS IT'S NOT PRACTICAL OR LEGAL.
Read the entire thread!
BTW, Hello VG, whazzzup[/QUOTEI].I have read your saying,and after that, I have a question to ask.
If someone breaks into my home,there are three possibilities.I have not any aid,human or mechanical to defend myself,I have a gun,or I have a strong laser.
What should I do,if the invasion is in the night,so I don't see the intruder very well,to understand if he is armed and dangerous?
Should I surrender saying, do what you want,to me and my wife and children?
I wait your answer with all do respect.
