7-year-old daughter, the suspect admitted that he had been giving her a
guided tour of the night sky. He faced a possible 20-year jail term but
ultimately was sentenced to two years of probation.Pilots' reports of
laser incidents have increased dramatically since 2004. The Federal
Airline Laser Pointer
(FAA) estimates that the total in 2015 could exceed 6,300.The incident
sparked a media frenzy, with many articles and broadcasts appearing
alongside other news from the War on Terror. Depending which newspapers
you read or which television stations you watched, you may have heard
that hand-held laser pointers — commonly available for less than $50
from a host of retailers and online dealers — are either perfectly
harmless or capable of bringing down a jumbo jet.Naturally, the truth
lies somewhere in between. Used properly, laser pointers are quite safe.
But used improperly or maliciously, they can be dangerous indeed. In
fact, the number of laser incidents reported to the FAA by pilots has
risen dramatically over the past decade. (One company now offers glasses
specifically designed to block green laser light.) Clearly, many owners
are treating these devices as playthings and don't realize the danger
they pose — both to pilots in high-flying aircraft and to others around
them at ground level.Here is some basic information about the laser
pointers typically used by amateur astronomers, along with some tips on
using them safely.
There is a class of Powerful Laser Pointer,
IIIa, which by law must be less than 5mW (of measured optical output,
not electrical input). This class is legal to sell in the United States,
and legal to operate outside in the United States (local or state
exceptions may exist) provided you don't do anything stupid. Shining the
laser at aircraft in flight, or moving cars, or other equally moronic
acts can easily land you in prison for an extended time (and rightly
so). Apparently a man who wanted to see if he could hit airplanes as
they were landing was in fact successful. Thankfully, none of the pilots
crashed, but the man was reported to have received a seven year prison
sentence.The next higher class, IIIb ranges from 5 to 500 mW. You can
also legally purchase this class of laser in the United States. But
there are restrictions on it's use, because these lasers are capable of
permanently damaging vision. You can't use it in an environment where
the beam could escape to the outside. To be explicit here, this means
you can't legally use them outside. Now you may want to adopt a "no
blood, no foul" attitude, and that's fine for you. But just know that if
you ever make a mistake, or run into a narrow-minded individual, you
don't have a legal leg to stand on - prepare for a good screwing.
Furthermore, based on my own <5mW product, there is no reason outside
of inferiority complex to get a higher power product for astronomical
use.

of this process: the first demonstration of laser-based adaptive optics,
a prototype, and the establishment of centers, the technology to build
the global telescope. But Max has become the biggest victory of her
biggest challenges. In October last year in other astronomers perhaps

University of California Observatory (UCO) temporary station chief. In
this position, regardless of temporary or not.
So how safe are these things (the sub-5mW class IIIa version)? They
won't burn you. They won't cause permanent eye damage. Tests were
performed on individuals who were scheduled to have an eye removed for
medical reasons. For the purposes of the test, the eye was normally
functioning. Test subjects stared directly at 5 mW lasers with there
to-be-removed eye for five to fifteen minutes from various angles. No
permanent eye damage occured. Some changes in tissue were noticed. Of
course, in a real-world incident, laser light entering the eye would
likely last for less than one second, as people naturally look away from
bright things and close their eyes, so there is no real danger of
direct damage.For some time applies in Germany:
Dealers in Germany may green laser pointers with more than 1 mW is not

Equipment and Product Safety Act (GPSG) only the safety and health of
users or third parties may products are placed on the market if when
used as intended or foreseeable misuse is not jeopardized. Therefore, to
be used in the private sector only laser devices in Classes 1 or 2

liability insurance will then step in this is questionable, since many

The pointers favored by stargazers use a neodymium diode laser and
emit a green beam at a wavelength of 532 nanometers. At a given power
setting, such lasers appear much brighter than the more common diode
lasers that produce a red beam at wavelengths longer than 630 nm. The
reason is simple: the human eye is much more sensitive to green light
than it is to red light.Except on nights of exceptional clarity and
near-zero humidity, if you shine a green laser pointer into the sky, you
can follow the beam hundreds of meters up. To you and anyone standing
around you, it looks like the beam ends at whatever star or planet
you're aiming at. This makes it really easy to show someone a particular
celestial object. Just point the laser at it and say, "Look there!"Most
laser pointers shine only as long as you hold down a button. But some
models have a "constant-on" setting. These are becoming popular as
pointing aids for telescopes. Once the laser is mounted and coaligned
with the scope, you just move the scope around till it's pointing at
your target star, and when you look in the eyepiece, there it is.The 20000mw Blue laser
in common use among astronomers and the general public have a power
output of a little less than 5 milliwatts; in the U.S., these are called
Class 3a lasers. Lower-wattage lasers, such as those in CD players and
laser printers, are Class 1 or 2, while higher-wattage units, such as
those in medical or industrial equipment, are Class 3b or 4. The higher
the class, the more severe the warning label required by the US Food and
Drug Administration (FDA).
