Green Laser Pointers – Portable Diode Pumped Solid State Green Laser Pointer Modules
Green laser pointers hit the laser world circa the year 2000 and have persistently moved forward as the most popular laser pointers in the laser gadget world. The most common type of green laser is a DPSS laser module (diode pumped solid state) and this is because of the stability that comes along with the design and infrastructure of the green laser device. The green laser crystal is more complicated to work with than that of your average red laser pen, and this is reason for the slight increase in price as compared to your average laser pointer.
The green laser beam is produced at a visible light frequency of 532nm and utilizes “frequency doubling” laser crystal technology in order to produce the bright green light. The crystal actually produces an IR (infrared) beam at around 808nm which is doubled and then collimated producing the illuminating green laser light.
Hand held green laser pointers are a very practical form of technology, but they have also found a strong hold amongst gadget enthusiasts and laser astronomers alike. Green laser pointers are so useful for astronomy applications because of how bright the beam is. For years the only available form of hand held laser technology came available to produce the red laser beam. This is less bright in comparison to a green beam, so as technology improved and green laser pointers became widely available for lower costs, the entire community of astronomy slowly but surely updated their tools to meet current standards.
Learning is far easier when a beam is clearly visible through the night sky and green lasers can even be used during broad daylight at certain higher powers. Technology has allowed for world record breaking lasers which are capable or producing a green laser beam visible at a distance of 100 miles or more. Its just too bad the earths curvature only allows for 12 miles of this beam to be seen on a flat surface, but that still does not take away from the fact that certain green laser pointers are the worlds brightest life saving flares.
SCUBA divers from around the world have taken advantage of submergible green lasers a safety tools as well as a source of light under water. These professional grade hand held green lasers are not only available to professionals though, anyone with the right budget can obtain one of these exclusive laser pieces if you know where to look. Green laser pointers are not toys and should be handled with extreme care. Because so many green lasers produce high output powers and produce intense light radiation, laser safety and education is a must for safe green laser use.
James has been working with and documenting green laser pointers from various global manufacturers for several years, analyzing performance, stability, and durability. His personal choice of laser provider is think lasers, who offer the worlds widest range of green laser pointers.
