I am working on an experiment involving gasses and induced fluorescence. I am under the impression that it is possible to induce fluorescence in certain gasses within the visible spectrum by using an infrared laser or by other means in the non-visible spectrum. Is this correct? If so, with which gasses is this the case?

In the little research that I have done about the topic, heavier noble gasses have been brought to my attention, such as Xenon and Argon.

The object of my experiment is to produce a small (eventually around the size of a computer pixel, but for now a dot is sufficient) point of visible light in a closed container of gas using induced fluorescence. Under ideal conditions, this would be done with some sort of laser or electron beam. If it is indeed possible to induce fluorescence in a gas in this way, would it also be possible to only excite the atoms in the intersection of two lasers? In other words, would it be possible to use two lasers instead of one, but only have the gas fluoresce where ther lasers met? My only ideas on this have involved something along the lines of using a specific frequency to excite the atom (perhaps its resonant frequency?) and tuning each laser to half of that frequency, so that at their intersection, the full frequency would be reached, and excitation, and therefore fluorescence, will occur. I've thought of numerous problems with this method, though, and I am wondering if there is any other way to produce this effect.

Please note that I am not particularly knowledgeable in chemistry, as I am only a sophomore in high school -- but also, I am most certainly not doing this for school. If you use anything that is much beyond the configuration of electrons and the basics of atomic theory, please explain it.

Any help would be greatly appreciated. Thanks.
