 When does Argon gas go into the "lasing" phase? What is the typical wavelength(s)of Argon gas during lasing? How much energy at which tempo is needed for lasing? Question Date: 2012-06-07 Answer 1:Emitting a laser is where the frequency of the light emitted by the excited atoms (containing excited electrons) stimulates the emission of more light of the same frequency, which is what the LASER acronym "Light Amplified by the Stimulated Emission of Radiation" means. The wavelength is determined by the amount of energy per photon, which is in turn equal to the drop in potential energy of the electrons falling to lower (unexcited) energy states. Different electron shells would make for lasers of different wavelengths, so presumably argon can make more than one different wavelength of laser with different states of excitement, but I don't know specifically for argon what those are. The formula for the frequency of the laser (which is the speed of light divided by the wavelength), is f = E/h, where E is the energy per photon and h is Planck's constant. Answer 2:I search on different sources of information in order to find useful information for you. Here you have the links which I recommend you to read. They are interesting and rich. From Wikipedia ion laser : Argon lasers emit at 13 wavelengths through the visible, ultraviolet, and near-visible spectrum, including: 351.1 nm, 363.8 nm, 454.6 nm, 457.9 nm, 465.8 nm, 476.5 nm, 488.0 nm, 496.5 nm, 501.7 nm, 514.5 nm, 528.7 nm, 1092.3 nm. From lexellaser The most prominent and most used wavelengths in the argon laser are the 514.5 nm green line and the 488.0 nm blue line. From Wikipedia Ar Depending on the optical design one or more of these transitions can be lasing simultaneously. Click Here to return to the search form.
