In a He-Ne laser system, the two energy levels of Ne involved on lasing action have energy values of 20.66 eV and 18.70 eV. The population inversion occurs between these two levels.
(i) What will be the wavelength of the laser beam produced?
(ii) What will be the population of the metastable energy level with respect to the upper excited level at room temperature (27oC)
