Helium Neon Lasers Selection Guide

Helium neon (HeNe) lasers are gas lasers which use a mixture of helium and neon to achieve optical gain. All lasers consist of three components: an energy source (or pump), a gain medium, and an optical resonator; these components are shown in the diagram below. Essentially, the pump provides energy which is amplified by the gain medium. Get price

Niagara College: Department of Photonics Lab

In the case of a helium-neon gas mix, the procedure to produce a ratio is to divide the total helium pressure by the total neon pressure (addition of both stable isotopes) to obtain the ratio for helium. If, for example, the RGA showed 2E-5 torr of helium and 2E-6 torr of neon the ratio would be 10:1 for Helium:Neon (which is the most common Get price
