Classification of the laser pen

 

Lumière green

The crystal non linéaire is excité by an infrared laser à 808 nm wavelength to générer a lumière ir à 1064 nm, and then redoubles for générer a lumière green à 532 nm, which belongs to a blue laser pointer solid. M&stop, me, the lumière green, low-power can &our vision to be seen at night because of the dispersion of Rayleigh molécules atmosphereédevices, which are often utilisées by the fans d’astronomy to point the étoiles and constellations. The green laser pointer can have several output powers. 5 mW is the most s&burn;r à use and visible under a élighting, strainersé, you do not need power for the score.

Lumière blue

À l’original, only the blue laser pointer 473 nm généré by DPSS, the power is low and unstable. While CASIO développait a projector high brightnessé with a source of lumière hybrid containing a laser diode, blue (445 nm), diode semiconductor blue d’a power supélimit à 1 000 mW (fourthème class) have été produced by série and popularisées.

Lumière red

Because there is a laser diode that produces the wavelength, its structure is more simple, it is simply a diode alimentée by a battery. The red laser pointer appeared for the première both in the années 1980. It s’acts d’unit éstandard and large d’a value of several hundred dollars; it is now small and not expensive. These lastères années, a red laser pointer à laser à état solid pompé diode (DPSS) with a wavelength of 671 nm is appeared. Although this wavelength can &our vision to be obtained with diodes little co&burning costly, the DPSS technology can produce lasers of qualité supéearlier and more éstraits.

Lumière purple

The use of a laser diode blue-violet of a wavelength of 405 nm belongs à a laser à semi-conductor, close to the strip of lumière ultra-violet and offer a low visibilité, but that can excite the fluorescence, and having the functions of contr&taxes;ler money and test the chemicals.

Lumière yellow

A pointer, yellow laser with a wavelength of 593,5 nm appeared on the marché. Two laser beams having a wavelength of 1064 nm and 1342 nm, are obtained by adding a crystal non linéaire basé on the technical DPSS. The complexityé this process makes the laser pointer yellow unstable and inefficient, with a power output ranging from 1 to 10 mW with the température, and a break mode in case of overheating or too cold. In fact, the size of the laser pointer does not provide the components of stabilization and cooling nénecessary. In addition, most of the laser pointers 593,5 nm operate in pulse mode to receive diodes of pump size and power inféinner.
