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
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.
Optical pumping is not efficient for helium-neon lasers because the energy levels involved in population inversion for the laser transition are insensitive to optical pumping. The pumping process does not efficiently promote electrons to the necessary excited state, limiting its effectiveness for helium-neon lasers.
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.
Laser radiation is typically produced using optical amplification of light, often from a stimulated emission process in a gain medium such as a solid, liquid, or gas. This produces coherent light of a specific wavelength which gives lasers their unique properties.
Solid-state lasers typically have higher power output compared to gas lasers. This is because solid-state lasers can efficiently convert electrical power into laser light, resulting in higher power outputs. Gas lasers, on the other hand, tend to have limitations in power scaling due to factors like gas flow and cooling.

A laser emits a beam of energy in the form of light. But to get energy out of a laser, we have to put some in. Depending on the type of laser, there are different ways to do this. What is important here is that the energy put into the lasing medium, the energy that is pumped into that medium to stimulate it, to excite it (the actual term), to induce it to lase, is supplied by an outside source, by a pump appropriate to that type of laser. So the pump, that thing outside the medium that stimulates it to induce it into lasing, is pumping when it is exciting the medium. Hope this was, um, coherent....

Gas lasers are a type of laser that uses a gas mixture as the laser medium to produce coherent light. The gas mixture is typically excited by an electrical discharge or other means to generate the laser beam. Gas lasers are used in various applications such as cutting, marking, welding, and scientific research.
To purchase gas using cash, simply go to a gas station, select the pump, and pay the attendant inside with cash before pumping your gas.
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
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.
its bad for the enironment
