The technology that we decided to work on for our project was lasers because we think lasers are a type of technology that has made our lives easier.
Lasers are possible because of the way light interacts with the electrons.
Electrons can be pumped to a higher energy level by an injection of energy, and a flashing light excess energy is given off as light. Lasers have many industrial, commercial and medical applications. Lasers are used for CD players and for even the most extensive surgery. They are used cosmetically with skin rejuvenation, they can also remove tattoos, stretched marks, scarring, blemishing, prevention from discoloration, and used in hair transplants. Construction applications use the beam of low power lasers as a guide.
