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...
