Lasers

Through photon camp in which I attended last year there was a lot of talk about lasers. This is because while using optics you can do a lot with lasers this is because you are easily able to manipulate them. The three things that all lasers have are an energy source, a medium and a resonator. The energy source or source pump is used to provide the laser with the energy that it needs to be powered. The medium is what really separates lasers because it determines the strength of the laser or the power that it has. And the optics are used to adjust and fine tune the beam. Lasers are cool because that have a variety of uses: cutting, welding, drilling, and marking. They are very good sources of light that are easy to manipulate and have endless uses.
