Question

Refer to Section 6.2 and show that, if the occupation number ne of an energy level is restricted to the values 0,1,., e, then the mean occupation number of that level is given by (me) = z-lede-1 e+1 (real)(+-1 (nc) Check that while 1 leads to(n.)FD, 1 → oo leads to (ne)BE.

    4.8 He-Ne Laser The He-Ne laser system energy levels can be quite complicated, as shown in Figure 4.58. There are a number of lasing emissions in the laser output in the red (632.8 nm), green (543.5 nm), orange (612 nm), yellow (594.1 nm), and in the infrared regions at 1.52 μm and 3.39 μm, which give the He-Ne laser its versatility. The pumping mechanism for all these lasers operations is the same, energy transfer from excited He atoms to Ne...
