Introduction
A Helium-Neon laser tube is a low-pressure gas filled glass cylinder with a pair of mirrors attached at the ends. It is a general laser device used in a variety of applications and it is also the most practical choice of economical gas lasers for beginners. A He-Ne laser is an ideal tool for alignment and education applications. It can be used in geometric optics, interference, diffraction and polarization experiments.
