What are Helium-Neon (He-Ne) Lasers? - GoPhotonics.com
Helium-Neon lasers are gas lasers whose gain medium consists of a mixture of helium and neon gases in the ratio 10:1 at a pressure of about 1 torr. They deliver an output wavelength of 632.8 nm which falls in the infrared region of the electromagnetic spectrum. However, other wavelength emissions ranging from 100 µm in the far infrared region to 540 nm in …
