Which one is the lasing material in helium neon laser?
The lasing material in a helium-neon laser is a mixture of helium and neon gases. The neon gas is responsible for emitting the red laser light when excited by the helium gas.
What two gases combine to form a laser?
An example is the helium-neon laser.
Helium neon laser ratio?
You need the gas mixture to be mostly helium, so that helium atoms can be excited. The excited helium atoms collide with neon atoms, exciting some of them to the state that radiates 632.8 nm. Without helium, the neon atoms would be excited mostly to lower excited states responsible for non-laser lines.A neon laser with no helium can be constructed but it is much more difficult without this means of energy coupling. Therefore, a HeNe laser that has lost enough of its helium (e.g., due to diffusion through the seals or glass) will most likely not lase at all since the pumping efficiency will be too low.
What colour is the light from helium-neon laser?
Red......................and eeeeeeeeerrrrrrrrrr how could you forget green too!!!!!!!!!!!!!
The helium neon laser is used for pdt as an aiming beam for infrared lasers?
yes
Why you use he in helium neon laser?
helium is used for excitation of neon atoms in helium neon laser..

What is the ratio of He and Ne in He-Ne laser?
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.
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 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.
What are the uses of different noble gases?
Xenon and neon are used in lighting. Helium-3 is used in fusion. Helium-4 is used in balloons (to make them float in the air). Argon is used in fluorescent bulbs and tubes. Helium and argon are also sometimes used in chemical reactions (laser ablation, laser epitaxy, etc.) where a steady stream of gas is needed to carry products, but not react with them. Helium and neon are also used in lasers.
The helium neon laser is used for pdt as an aiming beam for infrared lasers?
yes
What are some usual uses for neon?
Neon signs, and vacuum tubes, wave meter tubes, and helium neon lasers.
What are the future uses for the element neon?
-Red and Orange Neon Lights-Cheap Lasers (with Helium, Yttrium, Aluminium, and Iron)-Vaccum Tubes-High-Voltage Tubes-Television Tubes-Liquid Helium preserverit is used in neon discharge lamps and neon signs.
