In international humanitarian law, the use of laser weapons is prohibited when they are specifically designed, as their sole combat function or as one of their combat functions, to cause permanent blindness to unenhanced vision, that is to the naked eye or to the eye with corrective eyesight devices.
Even lasers with a power output of less than one watt can cause immediate and permanent vision loss under certain conditions, making them potential non-lethal but incapacitating weapons.
Lasers are already in widespread military use in range finders and target designators. Anti-sensor models, which could also be used against personnel, are a t an advanced stage of development. There are two types of " anti-sensor " lasers.
The Protocol on Blinding Laser Weapons, adopted in its current form on 13 October 1995 is the first instrument since the 1868 St. Petersburg Declaration to prohibit the employment of a weapon with perceived military utility before its use had led to streams of victims.
FOREIGN TACTICAL LASER WEAPON PROGRAMS. According to confidential U.S. government sources, Russia, China, Britain, France and Israel are known to have, or alleged to have, tactical laser weapon programs. Germany has also been mentioned in the military literature.
However recent amendments to the Weapons Prohibition Act 1998 require a permit be issued (or the person be eligible for an exemption) where the laser pointer exceeds one milliwatt. Regardless of the milliwatts, no laser pointer can be carried or used in a public place without a reasonable excuse.
If the laser pointer does not fall within the definition of a “prohibited weapon” because it is not over 1 milliwatt, then section 11FA Summary Offences Act 1988 (NSW) prescribes penalties of up to 2 years imprisonment and/or $5,500 fine for having or using a laser pointer in a public place without a reasonable excuse.
BLINDNESS HAZARD FROM DIRECT BEAM
The Nominal Ocular Hazard Distance for this nominal 1 watt, 1.0 mrad laser is 221 meters (725 feet). Beyond this distance, the beam is not expected to cause injury -- but still, NEVER LOOK INTO A BEAM NO MATTER HOW FAR YOU ARE FROM THE LASER.
Reflective Mylar is fine against visible light but not so good against an x-ray laser. ... Even the best mirrors do not reflect 100% of all radiation; some of the energy will still heat and eventually burn through the mirror.
At the latter level of intensity, a laser could deposit enough energy on a hostile ballistic missile during its vulnerable boost phase to destroy the missile.
"Magen Or" (Iron Beam) is the next step up in Israel's self-defense: a laser system that can "cook" rockets, missiles or drones from afar, and at zero cost compared to the Iron Dome.
Materials such as ceramic can absorb a beam's energy efficiently. But most coatings only work within a narrow range of laser wavelengths. Adding multiple layers of different coatings can help, but it can also block the missile's view and reduce the sensor's detection range and accuracy.
A military base deep in Western China is unusually active when foreign satellites are overhead—a sign that Beijing could be using laser weapons to electronically probe them. The Korla East Test Site, located in Xinjiang province, is believed to be home to at least two Chinese laser weapons.
While laser power of the order of 100 kW has been achieved, damage potential of the laser has been tested up to 800 m distance.
The agency takes enforcement action against people who violate Federal Aviation Regulations by shining lasers at aircraft and can impose civil penalties of up to $11,000 per violation. The FAA has imposed civil penalties up to $30,800 against people for multiple laser incidents.
The Consumer Products Safety Act prohibits the sale of these laser pointers that exceed the standard in Japan. However, there are, as yet, no restrictions on buying them overseas and bringing them into Japan or purchasing them from overseas online shopping sites and importing them directly.
If your camcorder can see the infrared light, then you should be able to see infrared laser beams using the camcorder's viewfinder or fold-out monitor. If someone is using a laser in the way you describe, this is illegal. It is damaging your property, cruelty to animals, and assault & battery.
Because IR lasers are invisible to naked eyes, there is no reflexive response to look away or shut them. This means exposure can take place without the victim even knowing it, causing serious damage or permanent blindness. So, it is clear why the sale of these devices is restricted.
And the overwhelming number of the incidents involved green lasers—especially dangerous because the human eye is most susceptible to damage from the yellow-green light spectrum.
The WHS Regulations prohibit the use of laser classes 3B and 4 in construction work. Laser classes that can be used for construction work are classes 1, 2, 3A, and 3B(Restricted). Although class 3B(Restricted) lasers can be used for construction work they should not be used in dimly lit work areas.
The observation
We used the world's strongest laser, the National Ignition Facility3 (NIF) at the Lawrence Livermore National Laboratory in California, to briefly create the extreme states of matter required for pressure-driven ionization.
Known as the Zetawatt-Equivalent Ultrashort pulse laser System (ZEUS), it produces an ultra-short, extremely powerful pulse of just 25 femtoseconds. A femtosecond is a quadrillionth of a second – or to put it another way, a femtosecond is to a second what a second is to about 31.71 million years.
