A comprehensive resource for safe and responsible laser use
Laser weapons in general
This page contains a link to an excellent article about laser weapons used against missiles, aircraft and other combat materiel. A separate LaserPointerSafety.com page discusses laser weapons used to dazzle or blind people.
In addition, these three links to News pages here at LaserPointerSafety.com list news items relating to laser weapons:
- Aviation-related incidents tagged with “Weapons”
- Non-aviation incidents tagged with “Weapons”

Overview of laser weapons and power
A good overview of laser weapons is an August 13 2016 article by Brian Wang at NextBigFuture.com, entitled “By 2021, combat lasers with hundreds of kilowatt power will demo shooting down ballistic missiles in the boost phase.” He covers many different laser weapon programs of the U.S. military.
He also has an excellent description of the laser power necessary to carry out various destructive missions. As you read this, recall that laser pointers in the U.S. must be below 0.005 watts (5 milliwatts), Class 4 lasers are those 0.5 watts and above, and the most powerful handheld lasers generally available to consumers as of mid-2016 are in the 2-3 watt range.
• Lasers with a power level of about 10 kW (10,000 watts) might be able to counter some UAVs at short range, particularly “soft” UAVs (i.e., those with design features that make them particularly susceptible to laser damage).
• Lasers with power levels in the tens of kilowatts could have more capability for countering UAVs, and could counter at least some small boats as well.
• Lasers with a power level of about 100 kW (100,000 watts) would have a greater ability for countering UAVs and small boats, as well as some capability for countering rockets, artillery, and mortars.
• Lasers with power levels in the hundreds of kilowatts could have greater ability for countering targets mentioned above, and could also counter manned aircraft and some missiles.
• Lasers with power levels in the megawatts (1 MW = 1,000,000 watts) could have greater ability for countering targets mentioned above—including supersonic ASCMs and ballistic missiles—at ranges of up to about 10 nautical miles.
A more recent article is from March 30 2017 by Patrick Tucker at Defense One, entitled “Why You Can’t Shoot Terrorists With Lasers, Yet”. The subhead is “Military leaders are eager to have the precision of a directed-energy weapon — yet plenty of legal and practical obstacles remain.”
Tucker notes the disjoint between the U.S. agreeing to laser weapons that don’t harm eyes, but also apparently legally being able to field laser weapons that kill. “All this leaves enough legal room to use lasers against people — if military leaders can be more certain about the effects that the weapons would have. That means, firstly, a lot more testing. ‘The deployment issue is less about the law and more about ‘Do I really believe it can do what you say?’,’ said [Mary] Miller [acting assistant defense secretary for Research and Engineering].”
