Goldwasser says that may not be a coincidence. The technical challenges of constructing a green laser are considerable compared to their red cousins, the professor explains. While a red laser involves essentially a single microchip, producing a green beam requires converting light from the original microchip into an infrared wavelength and then back into visible light. The inside of a Laser Pointer 50000mw , says Goldwasser, is a mess of "crystals, mirrors, and diodes — all kinds of stuff."
That complexity makes the cheaper models hard to manufacture reliably, so some companies seem to have compensated for poor quality control by simply dialing up the power. (No one wants a "wimpy" Laser Pointer Blue 30000mw, Goldwasser says.) The result is inexpensive pointers that are far more powerful than they need to be. The laser allegedly used in the incidents of March of this year, for example, packs about 200 milliwatts, far above the legal limit of 5 milliwatts. Goldwasser, who has testified as a defense witness in some lasing prosecutions, says the lasers on the market frequently are far more powerful than they're advertised to be.
The first and most important of all should be the clear application that you are in need of. Usually lower power red, blue, green 1mw Laser Pointer are generally used for presentation in teaching, lectures, speeches, PowerPoint, business conference, when a low power laser pointer with short distance visible laser beam has been enough. A green laser pointer ranges from 50Mw to 150Mw is always quite appreciate for astronomy.
In addition, it should be a key point for laser man to choose a genuine 50mw Green Laser Pointer from large variety of available laser gadgets. With the gradually matured laser diode technology, large quantity of green laser pointer has flooded into market. At the same time, the competitive price has made a lot of shoddy laser pointers gather into market with genuine lasers. How to separate genuine lasers from shoddy ones? Price doesn’t mean everything. A reliable reputation supplier is always a right choice for laser lovers and enthusiasts.
Whenever you are in need of a Laser Sight, you should always do more preparation and learn more basic knowledge before making a decision. You can always find a satisfying laser pointer from a reliable gadget at a reasonable price.
The forward visible and bright laser beam has provided a lot of convenience for astronomy researchers and enthusiasts for astronomy stargazing and constellation presentations etc. Meanwhile, high power red, blue, and green laser pointers are mainly used in military battle fields, scientific research, medical treatment as well as those entertainments such as burning or thermal experiments. As a result, you should always have a clear idea of what kind of application that you are in need of.
