A laser is a small but powerful focused beam. These beams are so powerful that they can perform many tasks that simple beams cannot. Since the birth of lasers, laser technology has been continuously developed and grown. Today, these powerful, focused beams are used for many purposes.
Lasers are used to amplify a light source and convert it into a powerful focused beam. Laser pointers need to be powered by a power source. You can use a battery, electricity, or other laser to power the laser. Lasers also need a medium that produces optical amplification. When the laser has energy and can pass through it, it becomes a focused beam. The beam is then radiated outward with a row of bright light. The term “laser” is an acronym for “radiation-excited optical amplification.”
