Helium–neon (He–Ne) lasers are a frequently used type of continuously operating gas lasers, which is also the first demonstrated gas laser (already in 1961 [1]). Most often, He–Ne lasers emit red light at 632.8 nm at a power level of a few milliwatts and with excellent beam quality .

Noble gas - Wikipedia

The six naturally occurring noble gases are helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and the radioactive radon (Rn). Oganesson (Og) is a synthetically produced highly radioactive element, variously predicted to be another noble gas, or to break the trend and be reactive, due to relativistic effects.


The helium-neon laser was the first continuous wave (CW) laser ever constructed. It was built in 1961 by Ali Javan, Bennett, and Herriott at Bell Telephone Laboratories. Helium-neon lasers are the most widely used gas lasers. These lasers have many industrial and scientific uses and are often used in laboratory demonstrations of optics.

Helium-Neon Laser

Helium-Neon Laser 1 Introduction The Helium-Neon Laser, short HeNe-Laser, is one of the most common used laser for allignement, reference laser and optics demonstrations. Its most used wavelength is at 632.8nm (red). It also has lasing transition in IR, orange and green. This experiment will make you familiar with basic


The speed of sound in helium is around three times the speed of sound in the air. This causes people's voices to get high pitched and squeaky when they breathe helium (note: never breathe helium as you can suffocate if you breathe too much). Helium has never been observed by scientists to bond with another element to form a compound.


Feb 04, 2007· Data Type: He/Neon Action: Submitted Note: In the attachment the helium isotope ratios are reported in d3He, percent anomaly from atmospheric values. The concentration data for helium and neon are reported in both cc/g (STP) which is the laboratory standard, and in nanomoles per kg, the WOCE reporting standard.

An important thing to note is that the inter molecular forces are rising with atomic size, and that's why helium has a lower boil than neon, preceded by argon, etc. Is helium used in medicine? Helium gas can be used to treat conditions like asthma and emphysema for respiratory ailments. Liquid helium also has a medical function, as it is used ...


The refractivity, however, shows a greater difference; for the admixture of helium and neon in the crude sample lowers the refractivity from 0.9665 for the pure gas to 0.961 or 0.960. In September, 1898, the discovery of another gas was announced; it was separated from krypton by fractionation, and possessed a still higher boiling point. ...

Note: Neon ordinarily has an eletron configuration of 1s22s22p6. The energy necessary to excite the Ne atom to the 1s2s2p55s state nearly matches the excitation energy of 1s2s (singlet) Helium. 4 One might think the amount of energy transferred to the Ne atom depends on how fast the two atoms collide with each other.
