How do the flash tube and the crystal make laser light?

1.A high-voltage electric supply makes the tube flash on and off.

2.Every time the tube flashes, it "pumps" energy into the ruby crystal. The flashes it makes inject energy into the crystal in the form of photons.

3.Atoms in the ruby crystal (large green blobs) soak up this energy in a process called absorption. When an atom absorbs a photon of energy, one of its electrons jumps from a low energy level to a higher one. This puts the atom into an excited state, but makes it unstable. Because the excited atom is unstable, the electron can stay in the higher energy level only for a few milliseconds. It falls back to its original level, giving off the energy it absorbed as a new photon of light radiation (small blue blob). This process is called spontaneous emission.

4.The photons that atoms give off zoom up and down inside the ruby crystal, travelling at the speed of light.

5.Every so often, one of these photons hits an already excited atom. When this happens, the excited atom gives off two photons of light instead of one. This is called stimulated emission. Now one photon of light has produced two, so the light has been amplified (increased in strength). In other words, "light amplification" (an increase in the amount of light) has been caused by "stimulated emission of radiation" (hence the name "laser", because that's exactly how a laser works!) 

6.A mirror at one end of the laser tube keeps the photons bouncing back and forth inside the crystal.

7.A partial mirror at the other end of the tube bounces some photons back into the crystal but lets some escape.

8.The escaping photons form a very concentrated beam of powerful laser light.

 

 

How is laser light different from ordinary light?

 

Lasers are more than just powerful flashlights. The difference between ordinary light and laser light is like the difference between ripples in your bathtub and huge waves on the sea. You've probably noticed that if you move your hands back and forth in the bathtub you can make quite strong waves. If you keep moving your hands in step with the waves you make, the waves get bigger and bigger. Imagine doing this a few million times in the open ocean. Before long, you'd have mountainous waves towering over your head!

 

A laser does something similar with light waves. It starts off with weak light and keeps adding more and more energy so the light waves become ever more concentrated. The "white" light produced by an ordinary flashlight contains many different light rays of different wavelengths that are incoherent (out of step with one another). But in a laser, all the light rays have the same wavelength and they are coherent (in step). This is what makes laser light such a powerful concentration of energy.
