The typical ratio of helium (He) to neon (Ne) in a helium-neon (He-Ne) laser is around 5:1, meaning there is approximately five times more helium than neon in the laser tube. Helium serves as the primary energy source while neon provides the lasing action to produce the laser light.

The mean property of a helium-neon (He-Ne) laser is its ability to produce a coherent beam of light with a specific wavelength in the red spectrum (around 632.8 nm). This laser is known for its reliability, long coherence length, and low divergence, making it suitable for applications such as alignment, interferometry, and barcode scanning.
The value of the thickness of wire using a He-Ne laser can be determined by measuring the interference pattern produced when the laser light is reflected off the wire. By analyzing this interference pattern, the thickness of the wire can be calculated based on the wavelength of the laser light and the angles at which the interference occurs.
A He-Ne laser is continuous because it operates in a continuous wave mode, meaning that it produces a steady output beam without interruption. This is achieved by the way the laser medium, helium and neon gases, are excited and release photons continuously, resulting in a continuous output of laser light. The stability and longevity of the He-Ne laser stem from the gas mixture maintaining a consistent excitation level, which allows for the continuous emission of light.
Mirrors are used in ruby and He-Ne lasers to create an optical resonator cavity for the laser to oscillate and produce coherent light. The mirrors reflect the emitted light back and forth within the cavity, amplifying the light through stimulated emission process. This process helps to establish the necessary conditions for laser action, where the light waves are aligned and reinforced to produce a powerful coherent beam.
A hene laser work using a tube filled with helium and neon gas, and two mirrors. When the gas is excited, one mirror reflects the laser completely, while one lets a smaller percent of the desired wavelength pass through which emits the laser.
The old laser printers used He-Ne laser , and the modern laser printers use infrared laser .

"Hene" is not a standard English word. It may be a misspelling or a word in a different language.

Helium gas serves as the active medium in a He-Ne laser. It provides population inversion between energy levels, allowing for laser action. The helium gas helps to excited the neon atoms to produce laser light at a wavelength of 632.8 nm.
The ratio of helium to neon gas in a helium neon laser is typically around 10:1. Helium acts as the gas that carries most of the electrons, while neon is responsible for emitting the laser light at a specific wavelength. This ratio allows for efficient operation and the production of a stable laser beam.

Helium-neon lasers are commonly used in barcode scanners, laser printers, holography, and alignment tools due to their stable output and low cost. They are also used in medical applications such as dermatology for skin treatments and in certain surgical procedures.
