because of gas in active center Neon gas worked as Active Center for He-Ne laser.to accelerate the Ne atoms very high and efficient Pumping is required. Which can only be given by Electric Discharge Pumping.

Why optical pumping cannot be used for helium neon laser?
Ans. Optical pumping methods are very ineffective for gas lasers because gas atomsshow sharp energy, levels as compared to solids, which are characterized by energy bands raTher than energy levels. Thus for gas laser the electrical discharge is used for pumping.
Helium neon laser ratio?
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.
Why electrical pumping is using for gas laser?
gas lasers do not usually lend themselves to lamp pumping because the absorption lines are typically much narrower than the usual broadband emission of the lamp. Electrical pumping of gas lasers ,on the other hand can be a fairly efficient process because the linewidth of excitation cross section of a given transition by electron impact is usually quite large
What two gases combine to form a laser?
An example is the helium-neon laser.
Which one is the lasing material in helium neon laser?
It is a mixture of helium and neon gases.

How is he-ne laser superior to ruby laser?
Helium neon laser is better than ruby laser or most of the four level lasers are better than three level lasers due to the following reasons: The laser output is continuous in the case of helium-neon laser. But it is in the form of pulse in the ruby laser. Ruby laser requires high power pumping source, whereas Helium-neon laser requires low power pumping source like electric discharge. Efficiency of helium-neon laser is more than ruby laser. The defects due to crystalline imperfections are also present in the ruby laser. But it is not so in the helium-neon laser.
Difference between he-ne laser and ruby laser?
1.he-ne laser is gaseous state. Ruby is solid state laser. 2.he-ne laser requires electrical pumping. ruby laser requires optical pumping. 3.he-ne laser has 4 energy levels. ruby has 3 energy level. 4.he-ne laser gives continuous output. ruby laser gives output in form of pulse 5. he-ne laser is cheaper
Why you use he in helium neon laser?
helium is used for excitation of neon atoms in helium neon laser..

Why helium is used in laser?
For power of cource
Which one is the lasing material in helium neon laser?
It is a mixture of helium and neon gases.
Which is better neon gas or xenon gas?
Depends on the purpose. But if you combine neon with helium, and obtain a helium-neon laser, you can see that it is much smaller than a xenon laser.
How population inversion is accomplished in laser?
by pumping electrons to higher energy orbitals.
What are the advantages of corona loss?
-it prevents conductor from electrical surges -it increases virtual diameter hence conductor can carry more current -corona discharge is used in photo copier and laser printers
