Green Pointer Laser --Introduction

Choosing the right type of green laser pointer can really be vital when you’re looking for the perfect tool that can be used during any presentation.  These are pointers that are just more powerful, and more ideal for creating a solid beam of light that can be utilized anywhere.

When you’re looking for the right type of green laser pointer, what you’re going to find is that they are much more powerful than other types.  That means you’re going to have a much clearer beam, that can shine much more solidly from long distances.

Of course, you also want to think about purchasing an ideal green laser pointer that’s really outfitted for your needs as well.  For example, if you’re just intending to use yours with computer presentations, you’re going to find that it can really be ideal when used combined with a mouse sensor.

What’s more, you want to ensure that you’re able to take care with your green laser pointer, to avoid any of the pitfalls of light this powerful.  The problem with lasers like these, is that the power they provide has a sinister side.

When you’re looking to buy the right type of green laser pointer, you’ll find that ordering online is usually going to be your best option.It’s just a matter of choosing the right type of green laser pointer, that you really know is going to be as useful as possible for you.

Green Laser Pointers And Aircraft

With the increasing popularity of high power green laser pointers, there are more and more reports of lasers being pointed at airplanes and helicopters. In 2008 alone there a number of reports that received wide spread media coverage. One such case in the United Arab Emirates capital of Dubai, two Arab men were charged, tried and convicted with pointing a laser beam at an aircraft during landing.

Background information on lasers

Very simply laser beams are very concentrated and narrow beams of light and lasers can have a range measured in tens of kilometers. A high power green laser pointer may have a range of 20 to 30 kilometers but it will not have any power or be dangerous at this range.reen laser pointers not red, blue or orange laser pointers are the main lasers pointed at aircraft because green is much more visible to the human eye than the other colors.

Real and imagined dangers

There are no commercially available and very few if any military lasers that can do physical damage to aircraft. The three main concerns and dangers to a pilot’s vision of pointing green laser pointers at aircraft is distraction, causing glare and temporary flash blindness.

In summary

For the laser hobbyist who does not deliberately target an aircraft, green laser pointers are safe to use out doors at night. A good precaution when pointing lasers at the sky is to first check the sky to make sure it is free of aircraft and avoid using green laser pointers around airports.

Green Laser Pointers Applications And Advantages

Green laser pointers were first commercially sold in the year 2000. They operate at the wavelength of 532 nm. Laser diodes of this wavelength are not available so the green light is obtained by the use of “DPSSFD” laser technology.

The process:-

A very high-powered Infrared laser diode working at 808 nm pumps a tiny block of Nd: YVO4 that generates light at 1,064 nm. This feeds a potassium titanyl phosphate intracavity frequency doubler crystal that produces green light of a visible 532 nm wavelength. High-powered green lasers use lithium triborate instead of KTP.

Features:-

An infrared filter, which is behind the mirror completely, removes the radiation of infrared spectrum from the output beam. In order to reduce cooling problems and prolong battery life, some green lasers operate in pulse or quasi-continuous-wave (QCW) mode. The Class III a laser product gives an output power of 5mw. This is the one of highest-powered street legal laser. Some green lasers even have an output of 10 mw, which has a range of 20,000 feet in darkness. Some even have a 3-second delay feature as these are high-powered lasers and can blind a person. Some laser point extenders are also available. They work by using lenses to minimize the beam spread of a laser. Its price starts from 55$. Majority of them have a life of around 3000 hours.

Applications:-

Green lasers can be used for a variety of roles. They can be used as pointing devices. The ability to form a continuous line in the dark is an added advantage; this has lead to its usage as rescue lights as it can be seen from miles away. It as been used for laser light shows. It is also used for sky gazing as a person can pinpoint a star by using the green laser. It can also be as laser pointers for guns, rifles. In the movie Alien vs. Predator it was used as a pointing device on some G36k carbines.
