About Laser Pointers

Laser pointers are compact instruments consisting of a low-power, visible light laser, used for pointing out features on a projected visual display.  They are often used in training and other educational settings to highlight data on a large screen, as well as in industrial settings for checking machinery and parts for defects.  Laser pointers are generally available with projected light in one of three colors, green, bright red (<650nm), or blue (650nm+).

Laser pointers are generally wand or pen-shaped and sized, and therefore easily portable.  Most types function using batteries, although some AC plug-in types are available.  The obvious difference between the two is that the battery-powered devices can be carried anywhere, while plug-in laser pointers are limited by access to a power source.

Products & Services Related to Laser Pointers

Diode Lasers
Diode lasers use light-emitting diodes to produce stimulated emissions in the form of coherent light output. They are also known as laser diodes.
Helium Cadmium (HeCd) Lasers
Helium cadmium (HeCd) lasers are relatively economical, continuous-wave sources for violet (442 nm) and ultraviolet (325 nm) output. They are used for 3-D stereolithography applications, as well as for exposing holographs.
Helium Neon Lasers
Helium neon (HeNe) lasers have an emission that is determined by neon atoms by virtue of a resonant transfer of excitation of helium. They operate continuously in the red, infrared and far-infrared regions and emit highly monochromatic radiation.
Ion Lasers
Ion lasers function by stimulating the emission of radiation between two levels of an ionized gas. They provide moderate to high continuous-wave output of typically 1 mW to 10 W.
Lasers
Lasers are devices that produce intense beams of monochromatic, coherent radiation. The word "laser" is an acronym for Light Amplification by Stimulated Emission of Radiation.
Nitrogen Lasers
Nitrogen lasers are an excellent source of high intensity, short pulse, ultraviolet radiation. They can be used as an excitation source, or as a pump for a dye laser.
Solid State Lasers
Solid state lasers use a transparent substance (crystalline or glass) as the active medium, doped to provide the energy states necessary for lasing.  Solid state lasers are used in both low and high power applications.
