Lite om Röd Laserpekare

This article deals with lasers in the red spectral region, ie the red laser with awavelength roughly around 625-700 nm. The following type of red laser is the most common:

Red laser diodes, based on such GaInP or AlGaInP quantum wells, are availablewith different output, ranging from a few milliwatts (single emitters, VCSEL) in the order of 100 W diode bars. Typical wavelengths are 635, 650 and 6

Lite om Blå Laserpekare

A so-called blue laser is a laser that emits electromagnetic radiation with a wavelength of between 360 and 480 nanometers, which the human eye perceives as blue light or light in the blue end of the spectrum. Diode lasers emitting light at 445 nm has become popular as a laser pointer. Laser that operates at wavelengths below 445 nm is perceived as violet to the human eye, an entirely different co

Lite om Grön Laserpekare

This article deals with lasers in the green spectral region dvs.med a wavelength roughly around 510-570 nm green laser. The choice of laser media for these wavelengths is limited, and performance can be achieved is usually not as good as for example in the infrared spectral region. But the green laser of different kinds are among the most widely used visible lasers.
