Construction of He Ne Laser. The Helium-neon gas laser system consists of a glass tube of nearly one meter in length. The gain medium in the He-Ne laser is a mixture of helium (90%) at 1 mm of Hg pressure and neon (10%) at 1/10 mm of Hg pressure filled in the glass tube. The reflecting mirrors M1 and M2 are fixed at the end of the tube.
Most powerful HeNe lasers emit 35 to 50 mW of output power. This is low comparing with a 100 mW to 200 mW TEM00 output from some semiconductor lasers. Even frequency stabilized 633 nm lasers emit 70 mW to 100 mW of narrow-linewidth power. Very bulky. A 35 mW output power HeNe laser is about 1 meter long.
A helium-neon laser, usually called a HeNe laser, is a small gas laser. Its usual operation wavelength is 632.8 nm, in the red portion of the visible spectrum. It is the most common type of laser used in physics laboratories. Its discharge tube is fitted with 80% helium and 20% neon gas. The neon is the lasing or active medium in this tube.

In He-Ne lasers, the optical pumping method is not used instead an electrical pumping method is used. The excitation of electrons in the He-Ne gas active medium is achieved by passing an electric current through the gas. The helium-neon laser operates at a wavelength of 632.8 nanometers (nm), in the red portion of the visible spectrum.

Answer (1 of 4): FTIR spectrometers have a HeNe laser that serves three purposes: 1- The IR detector samples asynchronously to collect the IR interferogram. This results in precise measurements of wavelength.
HeNe Lasers. Helium-Neon or HeNe Lasers are gas lasers that use a mixture of Helium and Neon as the gain medium excited by an electrical discharge. HeNe lasers are preferred for many optics lab applications due to their ease of operation and low cost compared to other laser types. Whether you need the flexibility of multiple wavelengths from a ...
Anode. The anode on the 155 is half way down the tube, SP157s and 159s actually use almost the same tube, but with the anode further down. This increases the length of the discharge/gain medium and results in a fairly big jump in power (up to ~5mW output). Looking down the tube. Unfortunately it does seem to have some power supply issues, it'll ...
In an inhomogeneously broadened laser, such as the HeNe laser, oscillation in various cavity modes occurs independently. When the spectrum is measured with an FPI, one sees lasing in many longitudinal modes, each fluctuating independently in frequency and amplitude due to mirror vibrations, mode pulling and other effects. These independent

The HeNe laser is built around a hollow glass tube with inward-facing mirrors and filled with 85-90% helium gas and 10-15% neon gas (the actual lasing medium) at a pressure of about 1 Torr (0.02 pounds per square inch (lb/in 2 )). The tube also has two inward-facing mirrors.
