Why electrical discharge pumping is used in helium neon laser?
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.
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.
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.
What are the uses of helium neon laser?
HeNe laser is used to determine the concentration of a fluid , its application is widely used in the engineering field, esp by chemical engineers. In a CSTR reaction, I myself used the HeNe laser to determine the concentration of the effluent reactants with the help of a detector. with the use of absorbency equations and little bit of math u can determine the concentration of your sample/reactants...etc.

What type of pumping is used in ruby laser and why?
This is kirit vaghela, The answer for the above question is that as far as ruby laser is concerned the pupmping is used is nothing but it is completed by optical pupmping.
What are the types of pumping in lasers?
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....
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 optical and laser mouse?
While both optical in laser mice require a light source in order to detect movement, the difference between the two technologies are optical mice use LEDs as their light source while laser mice use infrared laser that cannot be seen by the human eye. Laser mice are also much more precise than optical mice due to a higher DPI tolerance.
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..

Do they use a laser in an optical mouse?
Yes, that is a laser diode
What is the difference between a laptop wireless optical mouse and a wireless laser optical mouse?
The laser wireless optical mouse has laser sensors to direct the mouse on the screen as without it is a roll ball used to do so.
