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...

Electromagnetic Waves UV Radiation Some of us are all too familiar with the ill- effects of over-exposure to ultraviolet (UV) electromagnetic radiation, namely, sunburns (solar erythema). UV radiation can kill the skin cells immediately below the surface (part of the epidermal layer). Over the course of several minutes or several hours, as enough skin cells are killed or damaged, the body's natural immune response is triggered. The body responds to the damage with increased blood flow to the capillary bed of...
