This laser consists of a discharge tube in the cylindrical shape containing helium Neon gas in the ratio 9:1 at a low pressure. Two mirrors M 1 and M 2 are placed at the ends to facilitate the longer availability of emitted photons. A large potential difference is applied bet..

It consists of N turns of coil PQRS wound over a non-magnetic metallic frame usually rectangular or circular. The coil is suspended from a torsion head H by means of phosphor bronze strip in a magnetic pole by pieces N and S. A mirror M is attached to the phosphor bronze strip. The other..
