Green Laser Pointers Features and Applications-TradeTang

TradeTang Introduce the features, applications, advantage and disadvantage of Green Laser Pointer.
Green laser pointer for the first time commercial sales in 2000. They work in the 532 nm wavelength. This wavelength laser diode is not such a big green light, largely by "DPSSFD" the use of laser technology available.

The process:
A very high-power infrared laser diodes in the 808-nm pump of a small piece of Nd: YVO4 crystal, resulting in the 1064 nanometer light work. This diet with potassium interactivity frequency doubling crystal, producing a clear green light wavelength of 532 nm. High power laser pointer green instead of using three lithium borate KTP's.

Features:
An infrared filter, it is entirely behind the mirror, removed from the output beam of infrared spectral radiation. In order to reduce cooling problems and prolong battery life, some green laser pointers working in pulsed or quasi-continuous wave (quasi-continuous) mode. The third type of laser pointer products can make a 5-mW output power. This is the highest law of the streets of laser-driven one. There were even some green laser pointer is 10 MW, including one in the dark within 20,000 feet of output. Some even as these high-power lasers pointers can blind a person 3 seconds delay function. Some laser pointer spread provision. They work with the camera in order to minimize the spread of the laser beam. Since its price from 55 dollars. Majority of them have about 3,000 hours of life.

Application:
Green lasers pointer can be used for a variety of positions. They can be used as a pointing device. Can form a continuous line in the dark, is an additional benefit, which led to the use of light as a rescue, because it can be seen from miles away. It was used as a laser show. It can also be used as a human being can be targeted using a concept of green laser stars of the sky. It also can be used as a pointer laser guns, rifles. Alien vs Predator in the movie it was used as a pointing device of some G36k carbine.

Advantages:
Green laser pointer has many advantages. This is 50 times the red laser, because it can be seen from miles away, the light, which is helping to save a person who is lost. It can also be used in high-tech weapons targeting purposes. Because of its high range, green laser pointer can be equipped with different types of weapons. High temperature does not affect the performance of the green laser pointer case is the one who lost in the desert, he can still use the green laser pointer for help, in other cases, even if a person loses a number of places in all the snow-covered mountain, he can still use it.

Disadvantages:
Because of its high power can permanently damage a person's eyes. Because it can form a light may reveal a person's position, it can not covert action or by the special police used the same strain.

Green laser Pointer is quite terrific, but should be used with caution.

TradeTang Tell you How to Choose a Quality Green Laser Pointer

The article reminds people of doing a little study on the two key specifications of a green laser pointer or 300mw green laser torch before they spend their hard-earned money on any eye-catching item.

People are often at a loss when thinking of ordering anything on-line, because there're too many options except what they seek is the rarest thing. In this times of mass production and imitation, even if the customer is in vote when it comes to the matter of quality, nobody wants to waste any time or dollar on a crappy laser pointer or handheld laser pointers. They all think twice before clicking the "add to cart" button on those eye-catching online shops. Don't judge a laser by the ads or the dazzling logo or casing, and try to see something inside. That's why we need some insider information about how to choose a quality laser pointer.

The first specification we need pay attention is whether the handheld laser ponter by which we're attracted is equipped with an ir filter. An infrared filter, or IR filter for short, is used to block the passage of infrared radiation while allowing other radiation types to pass. Clamours about the importance of adding ir filter to each 532nm green laser pointer or 473nm blue laser pointer becomes a yardstick in judging a quality laser.as far as laser safety is concerned, it's recommended to buy ir filtered lasers because you can at least keep your eyes safe if you wear the right goggles for green laser beam. Despite not being visible, IR rays can still pass through the anterior structures of the eye and reach the retina. Since you are unable to detect IR, there will not be any blink or aversion reflex to protect your eyes from damage. But you certainly can wear 600-1100nm to block the ir laser beam for safety's sake.

The second specification we need study is the beam divergences, which is closely related to the beam diameter, which, just as the as the name suggests, is just the diameter of its laser beam, measured in millimeters. It's decided by the beam divergence which measures how much the laser beam expands per meter. It's easy to conclude that the smaller the laser beam, the farther it could go, the more intense, the beam power is, but generally speaking, the higher the output power is, the bigger the beam diameter becomes. Therefore, the laser pointer does not have to be small to be more powerful. It can also be supposed that these two key specifications are unable to grow at the same time; in other words, the decline of one means the growth of the other. This point is also specified in the laws of optics.

That's why most laser professionals insist that when it comes to the choice of a better 50mw or even 300mw green laser pointer, the smaller the rated beam divergence is, the better.
