The red laser beam is the original light frequency to be widely used for the design and production of red laser pointers and red laser pens at 650nm. At their first global recognition, the red laser created quite a buzz amongst various scientific and professional communities. The idea of visible dense light radiation in the convenient form of a hand held laser pointer was truly revolutionary, so when the red laser diode was stable enough for portable laser use, many laser manufacturers and technicians began a global laser light symposium.
So many different varieties of red lasers soon became available as more and more companies and scientists tested their hand in the production of better and more powerful red laser diodes. Soon, you could find all sorts of red laser pointers, red laser keychains, red laser pens in various stores or in gadget magazines, and eventually online. But red laser pointers have been around a bit longer than the internet, and for a while, people would literally be selling cheap red laser pointers on the street for anyone and everyone to buy. It was every childhood boys fantasy to get a red laser pointer and pretend it was a laser scope or a military laser pointer. So many dreams were fulfilled by cheap laser pointers that would include end caps and lenses for your cheap keychain laser. But good dreams die hard, and more often than not, the red lasers would burn out or be confiscated by wary parents.
Finally, the modern world has caught up with laser technology, and 650nm red laser pointers can be found all over the web from a variety of retailers in all sorts of different laser pen models. These have quickly become some of the most popular high-tech gadgets to hit any global market. If you have ever visited a laser pointer forum or a gadget message board, you may find stories and tales of self proclaimed geek's using their red laser pointers for all sorts of interesting applications. A few quick searches on youtube for red lasers can yield a surplus of home made laser videos showing off their laser pointer pens power and color.
