Security issues and green laser pointer

In the past, there have been a lot of discussion about green laser pointer.They are a great tool, amateur astronomers, however, is worrying the government, a terrorist could attempt to cause the plane crash, positioning a laser.This is a very funny, I have a lot of reasons, but because the laser pointer is very commonly used in amateur astronomy community, I want to know the truth before I bought a better.Here's what I found out:
Laser pointer commonly used by amateur astronomers are green, continuous wave laser light centered at a wavelength of 532 nm.They asked the FDA warning or danger sticker in their representation of equipment, which in turn depends on the maximum output device.FDA control equipment, because they may cause damage to the eye.Most amateur laser pointer is not two (output = 1 MW) and IIIA (output = 5 MW) equipment.Although the industry needs to label their products description, randomized trials have shown that, some of the equipment over its flag output.Therefore, study described below for the correct level of output.
FDA has studied and published to the human eye and related injury during laser irradiation.These studies indicate that, tissue damage may occur when the eyes are exposed to a class of IIIA 5 MW green laser at a distance of 10 feet or less.This point alone should cause astronomers understand these laser should be handled carefully.Although the eye tissue injury is a serious matter, this is not the key problems and the United States Federal Aviation administration.On the contrary, they are concerned about the glare, flash blindness and imaging when a pilot is exposed to laser.How much will affect the unit and the degree of exposure to tolerate the aircraft during take-off or mode of the United States of America exposure of faa.
Security is a big problem at present.Now, the laser pointer is easy and relatively inexpensive and they do everything in one's power in the range of most people.But unfortunately, some are for children, this is not good.
Children are children, often they don't really know what they are doing and their pointers can be dangerous.It is not just their points to them, but they look at the beam with the naked eye, this may be the eye's retina damage.
Importantly, they are not toys, so they should not enter into the hands of children, unless there is a responsible adult supervision.Even so, the accident may occur the child may suddenly put eye damage Liang and bingo you likely.
It is a great pity, some potential is tremendous fun and experiment, which improve the hologram can quickly become a dangerous thing.
This leads to many advantages of the laser is prohibited in many countries, as we all know, causing the pointer is illegal imports into the country, they are prohibited.Many suppliers are not be timid and overcautious, display pointer real strength.
