The idea for the laser started as long ago as 1905 when Albert Einstein suggested the simulated emission of light. Light sources ie. candles, florescent substances, torches, and light bulbs give of packets of energy, called photons, when their atoms are excited by energy.

Laser Applications
The use of lasers is wide spread and is now days becoming a commonly known tool. Lasers have become valuable tools in industry, scientific research, communication, medicine, military technology, and the arts. Lasers now days are used in operations for medicine, welding in industry and most commonly, as tools to point out objects (laser pointers).
