Green laser pointers are significantly brighter (about *0 times) than a red laser pointer and because of its unusual color it is much more noticeable. Just about everyone has a red laser pointer, but we're pretty sure you want to own the very best - and doing it with a green beam laser is the way to go. A **2 nm green laser wavelength is obviously superior to a laughable **0 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. 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. Since green direct injection laser diodes aren't readily available, this pointer is based on the use of Diode Pumped Solid State Frequency Doubled (DPSSFD) laser technology. A high power IR laser diode at **8 nm pumps a tiny block of Nd:YVO4 generating light at 1, **4 nm which feeds a KTP intracavity frequency doubler crystal to produce the green beam at **2 nm.
