Problem 5: This problem deals with gases used for a He-Ne laser. Consider the Neon transition at 632.8 nm. The upper level of the transition (with respect to ground level of Neon) coincides with a 2s level of Helium that has the energy of 20 eV with respect to the ground level of Helium. The gases are kept at room temperature (300K). We consider only three different energy levels of Neon: ground level, lower level of the laser transition, and...
