Green laser pointer move forward fast from 2000, and become the most popular laser gadgets among the laser world. A DPSS laser module (diode pumped solid state), that comes along with the design and infrastructure as well as the stability feature become the most common type of green laser. The price of green laser is a little higher than the average laser pointer, but it is still reasonable, because the green laser crystal, when it is working, is more complex than the red laser pens.
Frequency of 532nm is a visible light beam of green laser is also used a bright green light "frequency doubling" of the laser crystal technology. The crystal structure is indeed collimated light produces a bright green laser at around 808nm to double IR (infrared) and then collimated producing the illuminating green laser light.
For the years, the laser technology can only produce the read laser beam, and the time with the red laser the only hand held laser has gone. Now as the technology improved, a green laser beam is much brighter than the red ones, and with it become widely available, the costs become lower too. Laser pointer is actually the astronomy tool, though develop slowly but continue to update and will finally meet the stands currently.
When the technology make a beam become clearly visible in the night sky, it can make the learning become much easier. And when the green laser can in a particular higher power, it can even be used in broad daylight. Technology allows the laser to break the world record to produce a green laser beam with visual distance of 100 miles or farther. It's just too bad the planet, only allowed 12 miles bending beam, when which is in a plane, but it still does not take away the fact of that some green laser pointer is the world's most bright of life-saving bombs.
You may want to get a laser pointer, when you find it is commonly used for medical, scientific and military fields, and you can get one from the well-known online retailers of lasers easterly. But remember it is the high-tech equipment and should not be used as toys, because, if used improperly, the green laser beam can be very dangerous. This is the more important thing you should keep in mind.
