Spectral Bands of Noble Gases

  1. Sep 5, 2014 #1
    Is it possible to manipulate a noble gas to produce any line in its emission spectrum for a ? For example, argon produces blue but it also has several lines of red, can one force the argon to emit the red bands?

    A single emission line is difficult, but may be possible. The closest I know of is something like a helium-neon laser which emits mostly at two emission lines of neon. I believe one of these emission lines is suppressed so that most of the laser power is emitted in the other.

    Yeah, if you have a laser cavity, just put a filter for the appropriate wavelength, and this wavelength will be amplified while the others are attenuated by the filter.
