Green Laser Pointer Pens Are Much More Cooler Than Red Laser Pointers
Everyone of you should have played around with a laser pointer. Maybe you used one for work, when for a Power Point presentation. Or to tease your cat or dog, make fun of your friends by planting a red dot in their forehead, and much more funny things.
But, let’s face it, common red laser pointers are just so lame now. Everyone has one. Your mother has one, and she doesn’t even know what Power Point means. You need a new toy to make you the top geek at work and make fun of your friends…
Now, take a look at this green laser pointer pens. And we don’t mean that “green” where everyone is recycling their old papers. We are talking about a very cool new laser pointer with the much more powerful 532 nm wavelength; which, as any geek worth “his or her salt” knows, is tons better than the old 650 nm used by the old lame red laser pointers.
So if you got your kicks by using your old red laser beam to highlight things on a projection screen across the room, imagine how much fun it will be using a green laser pointer pen to point on things that used to be out of your reach. Because a green laser beam is much more powerful than a red one, it can highlight clouds, and even star constellations.
Best of all, you can see the green laser beam outside during full sunlight!
In fact, if you use this laser outside and happen to point it at an airplane, it’s so powerful you will find yourself in big trouble with the government because pointing a sighting device at a plane could get the feds investigating what other reasons you might have for pointing a powerful laser beam at planes.
Furthermore, the green laser pointer pen doesn’t produce a tiny little spot. Oh no, it turns out that your green laser lets you see the whole beam as it travels to the stars.
A green laser pointer is at a whole separate plane from the red laser pointer. For a true green, a pointer needs a green direct injection diode. These diodes could be potentially dangerous if handled by the public at large, so they’re not even available for wholesale.
Technology called Diode Pumped Solid State Frequency Doubled (or DPSSFD, for short) is what is used for a green laser pointer. This is the technology behind one of the pointers you can buy at the store today. An infrared diode emits 808 nm, which is transformed into 1,064 nm and fired into a special crystal that increases it to two times its frequency. That is where the green 532 nm beam comes from.
