What are the commonly used laser pointer colors?
While red lasers are still the most commonly used in homes, blue and green high power laser pointer are growing in popularity. These alternative laser colors have higher power levels and you can use them for remote tasks. Home laser pointers sometimes come with spare heads to modify the beam. These allow the projection of simple lines, points and images rather than the traditional landmarks of standard lasers. Other laser pointer accessories include a lanyard for better control and a protective case for shipping. Green laser pointers are more productive in astronomy class, while red ones can handle many everyday tasks. What has changed is the availability of a powerful laser pointer. About a decade ago, red-light pointers sold for about $600.

If you're looking for a laser pointer or have some basic understanding of how the light spectrum works, each visible color has a specific wavelength (or frequency) that indicates the actual length of the wave itself. Low wavelengths are long wavelengths of UV light, such as 355nm UV lasers, that are invisible to the human eye because they are not part of the visible spectrum. Lasers are everywhere in life. A laser tells a grocery store clerk the price of a loaf of bread. Lasers are used in stores to track inventory, hang photos directly at home, weld on car assembly lines, in operating rooms, in the military for laser-guided weapons, and in common electronic devices such as CD players. For example, if you're using a green laser pointer from 200mW to 532nm, a pair of laser glasses that protect 880nm resolution won't do you any good, since they're designed to block only 880nm resolution and may even make the exposure worse. The low-power laser pointer chooses the pen-type design, and the high-power green laser pointer chooses the manual flashlight design to obtain more space for the larger laser module. High power pocket lasers require more space as thermally stable systems. Pocket lasers always add the ability to adjust focus protection and security keys.
