Helium neon laser working and applications Physics

WORKING PRINCIPLE. In the He-Ne laser, light is produced by the atomic transitions within the neon atom. Since the helium does not directly produce the laser light, but it acts as a buffer gas. It’s purpose is to assist the atoms of the other gas to produce lasing in a manner. When the energy from the pumping source is applied to the He-Ne gas mixture, some of the energy is observed by

In the earlier articles, I have explained the construction of helium neon laser. Today let us discuss the working of helium neon laser: Pumping of He atoms: When electric discharge is passed through the gas mixture of He and Ne, electrons are accelerated down the discharge tube in which mixture of He-Ne …

Abstract. Isotope effects in the two-mode operation of a 633 nm He-Ne laser are investigated with due allowance for soft collisions. A theory is developed for the power of and beat frequency between two modes as a function of cavity detuning with and without soft collisions.

Low-Energy Helium-Neon Laser Irradiation Stimulates

In He-Ne laser, neon atoms are the active centers and have energy levels suitable for laser transitions while helium atoms help in exciting neon atoms. Electrodes (anode and cathode) are provided in the glass tube to send the electric current through the gas mixture.

A double longitudinal mode He-Ne laser with frequency stabilization is proposed. Compared with general methods, such as Lamb dip, Zeeman splitting and molecule saturation absorption method, this design has some advantages, such as no piezocrystal or magnetic field, a short frequency-stabilized time, lower cost, and higher frequency stability
