HTPOW 200mw green laser pointer bursting a balloon instantly
The first and most important aspect of our 520nm 1000mw Laser Pointer is that they are direct-diode semiconductor lasers. This means the laser beam is emitted directly from the laser diode from the semiconductor. 532nm green laser pointers, on the other hand, are DPSS lasers that are more complex in construction. In fact, 532nm green lasers don't even contain a green laser diode, instead, inside a 532nm green laser module is a 808nm infrared laser diode. By "diode pumped", a DPSS laser typically use an infrared power source to "pump" laced crystals where the wavelength is manipulated to becoming a different color, for our purposes, green.
The green laser pointer in common use among astronomers and the general public have a power output of a little less than 5 milliwatts; in the U.S., these are called Class 3a lasers. Lower-wattage lasers, such as those in CD players and laser printers, are Class 1 or 2, while higher-wattage units, such as those in medical or industrial equipment, are Class 3b or 4. The higher the class, the more severe the warning label required by the US Food and Drug Administration (FDA).
This allows the green laser pointer to be used for pointing to star constellations (skypointing) and also just generally look cool as hell. The green laser beam dot can be seen at much greater distances than with a red laser pointer.A 532 nm green laser pointer wavelength is obviously superior to a laughable 650 nm red laser wavelength. And unlike a red laser, the green beam itself can be seen in mid-air in dark conditions, not just the laser beam dot.

Tobares and M. Dowell. Random testing reveals excessive power in commercial Red Laser Pointer pointers.Journal of Laser Applications. (Forthcoming.). This 635nm, adjustable focus red laser pointer is the #1 red laser pointer of choice among chiropractors, acupuncturists and other healers for take home Low Level Laser Therapy.Also, it is difficult to hand-hold a laser onto a moving target, so the exposure time may be brief (the pilot sees bright flashes rather than a steady light).
The laser injuries Dr. Shepard Bryan has seen at his practice in Mesa, Ariz., involved red lasers, which laser fans like Mr. Triano consider pass. Green is more easily perceived by the eye and the beam is visible along its path.
The further a person is from the laser source, and the shorter the time that the laser light is on the eye, the less chance of eye injury. This is why a handheld laser that could pop balloons, ignite cigarettes or cause instant eye injuries at close range, probably would not be able to cause even minor eye injuries to a pilot flying an aircraft. The pilot's eye is much further away (a laser beam does spread out with distance, so not all the light goes into a pilot's pupil).
