Things to know

We talk straight. Nevertheless, the use of technical terms is unavoidable. Here you will find the most important terms.

He-Ne laser

The helium–neon laser or He-Ne laser, belongs to the gas lasers. The active medium is a mixture of helium and neon inside of a small bore capillary tube surrounded by a larger tube as gas reservoir. It is pumped by a high DC voltage that causes a gas discharge. The He-Ne laser is manufactured for more than 50 years without major design changes.
