Byte av HeNe-laser (AR550). LASER betyder ljusförstärkning genom stimulerad emission av strålning. En laser är en mycket Typisk laser: Gaslaser, t.ex. helium- och neongas (HeNe-laser).

Most powerful HeNe lasers emit 35 to 50 mW of output power. This is low comparing with a 100 mW to 200 mW TEM00 output from some semiconductor lasers. Even frequency stabilized 633 nm lasers emit 70 mW to 100 mW of narrow-linewidth power. Very bulky. A 35 mW output power HeNe laser is about 1 meter long. 2019-12-04 · Thorlabs offers an extensive selection of CE compliant 632.8 nm (red) Helium-Neon (HeNe) Lasers with powers from 0.8 mW to 22.5 mW from stock.

Lasers in which a gas lasing medium is stimulated to emit light by an electric current or high-frequency oscillator.

Section 1. Background A laser is an optical oscillator and thus consists of an amplifier with positive feedback. The amplification in a He-Ne laser arises in the glow discharge while feedback of the optical radiation is provided by two highly reflecting, well aligned mirrors. A helium-neon laser, usually called a HeNe laser, is a type of small gas laser.
