What are lasers?
Laser is an acronym for light amplification by stimulated emission of radiation. To your eye, the light from even a small laser can be brighter than the light from the sun.
Laser pointers are handheld lasers that are used during lectures of demonstrations to draw attention to a specific area of an object or projected image.
Are lasers dangerous?
As mentioned, lasers can be very bright! High power lasers can burn skin and ignite clothing. Fortunately, laser pointers are medium power so they cannot burn skin or ignite clothing. Medium and high power lasers can damage your eyes before you can blink, therefore, the beam from a laser pointer should never be pointed at anyone at any time.
Lasers are classified by the radiant power and wavelength of the light they emit:
Class 1 Laser. A Class 1 laser is considered to be incapable of producing dangerous radiation levels and is therefore exempt from most control measures or other forms of surveillance.
Class 2 Laser (Low Power). A Class 2 laser emits visible radiation (400-700 nm). Eye protection is afforded by the normal human aversion response to bright radiant sources. This type of laser may present some danger if viewed directly for periods exceeding the 0.25 second aversion time. The "Class 2a" classification was developed for supermarket bar-code scanners; Class 2a lasers are not intended for viewing but are not hazardous if viewed for up to 1000 seconds. Class 2 does not apply to lasers radiating at wavelengths less than 400 nm or greater than 700 nm.
Class 3 Laser (Medium Power). A Class 3 laser is hazardous under direct beam and specular-reflection viewing conditions, but the diffuse reflection is usually not a hazard. A Class 3 laser is normally not a fire hazard. Ultraviolet (UV) and infrared (IR) lasers that emit invisible beams (<400>700 nm) are always Class 1, Class 3 or Class 4. Class 3 lasers are divided into two subclasses, 3a and 3b, each having slightly different control requirements.
Class 4 Laser (High Power). The direct beam, specular reflection and diffuse reflection from a Class 4 laser are hazardous to the eye and skin. A Class 4 laser can be a fire hazard.
When laser pointers were first introduced, they were normally class 2. During the last few years, the power of laser pointers has increased so that they are now typically class 3a. These have the potential to damage the eyes.
Safety concerns
Flashblindness can result if the eye is exposed momentarily to light from a laser pointer ?this effect is temporary. It is like the blindness and disorientation that can occur when a camera flashes close to your eyes in a darkened room. A longer exposure to a class 3a laser can cause permanent damage to the eye. The eye is at greater risk when using optical instrument (e.g., binoculars). This could be a potential problem when laser pointers are misused at rock concerts or sporting events.
The misuse of laser pointers has been reported in many countries, including Canada. As the price of the laser pointer has dropped, the frequency of these reports has increased. Saskatchewan Labour抯 1999 survey of vendors in Regina and Saskatoon showed that there are few controls on who may purchase a laser pointer.
The survey showed that most vendors of laser pointers were not aware of the risks associated with their use. This could explain why the laser pointers were often marketed as a novelty item rather than a visual aid for making presentations. The survey results also indicated that many laser pointers do not meet the labeling requirements of The Radiation Health and Safety Regulations, 2005.

Recommendations
Vendors and owners must comply with The Radiation Health and Safety Regulations, 2005. This includes ensuring that lasers are properly and clearly labeled and, in the case of Class 3a, 3b and 4 lasers, that all reasonable precautions are taken to ensure that no person is exposed to the direct beam or the specular reflection of the beam. In the case of Class 3b and 4 lasers, precautions should also be taken to ensure that no person is exposed to the diffuse reflection of the beam.
In order to minimize the misuse of laser pointers, it is recommended that vendors of laser pointers implement a policy which:
a) restricts minors from purchasing lasers;
b) informs purchasers of their responsibility under The Radiation Health and Safety Act, 1985; and
c) ensures the following written caution is prominently displayed where laser pointers are sold.
CAUTION: Laser pointers can be dangerous. They should be used cautiously and only for their intended purpose. Laser pointers are not toys and should be kept out of the reach of children. In no event should the laser beam be directed at people or at surfaces that could reflect the laser beam directly at people.

Green Laser Pointer From Warnlaser
-- The King of the laser pointer kingdom --
Enjoy now the Supreme Power of the Green Laser Beam
God made two great lights; the greater light to rule the day, and the lesser light to rule the night ( Bible*Genesis, 1:16). And after his kind the scientists of Warnlaser made after years of researching and development the Green Light Amplification by Stimulated Emission of Radiation. The Green Laser rules not only the laser pointer kingdom, but also really rules the night.
Have you panned out your own Green Laser Pointer?
Maybe you are looking for around the King of laser pointers, Warnlaser is ready to open here the door for you to touch the King -- Green Laser Pointer that surely can make you really DISTINGUISHING.
A green laser pointer from Warnlaser has the best centralized light dot and the most beautiful green beam which can be seen, like a green sword elongated by David Copperfield, in the midst of the firmament in the night. Comparing to the yellow, blue, red and purple laser, with noblest emerald-like color and approximately 80 times brighter than the red laser, a Green Laser Pointer is a diamond comparing to a stone crystal.
Well, as a photoelectric product, what technology supports a green laser pointer? Right! It is DPSSFD --Diode Pumped all-Solid-State Frequency Doubled technology. An 808 nm high power laser diode pumps a tiny block of Nd:YVO4 generating light at 1,064 nm by which a KTP intracavity frequency doubler crystal is backed to produce the 532 nm green laser beam that isn't easily disturbed, unlike the red laser.
How to use a Green Laser Pointer?
A Green laser pointer ＜20mw is good enough to be an assistant to a tutor who can easily show the context on the blackboard any where in the classroom by using it as well as it plays an important role in the business seminar when you're an instructor.
A Green laser pointer ∈[20mw,50mw] can surely help you strut your stuff when you a guider have to show the visiters the objects at an exhibition spot which seem too high to touch and too big to view and too far to see.
A Green laser pointer ＞30mw of Storm Series and Explore Series which are showerproof, moistureproof, tough and excellently stable even if the temperature is changed extremely is designed specially for pointing to an object in long distance as well as for lighting and signalling in dark condition when travelling and exploring. And
it is better to use it to point to a dangerous object when mining underground and building a mansion / a great bridge.
A Green laser pointer ＞30mw of Tiger Series lives for birdwatching and pointing to star atlas.You must be amazing when the brilliant green beam shooting in the twinkling sky.
We not only provide Green Laser Pointers but also create room and space for you, because that you could create the other kinds of usages of Warnlaser green laser pointer when fishing, enjoying DISCO, and when you control a Green Laser Pointer, you are ruling the space wherever the green laser beam goes through.
The other interesting items also are available, such as of astigmatism, lange-angle, the shortest diameter but the brightest beam, and power＜5mw.
Now you may wonder what quality of green laser pointers Warnlaser can provide? That is the very point we most care about. Green Laser pointers from Warnlaser are ROHS、FDA、CE、TUV Certified, with high radiosensitivity. In light of your imaginable special taste, we'll continuely devote extra efforts to perfecting every details to match your standard. So far, we've developed Six Series of Portable High Power Green Laser Pointers as below. If you have any request and question, please contact without any hesitation Warnlaser team which are ready to serve you any time, by which we can improve in time our products and technologies as return to par with your need.
