A laser is a device that produces a narrow and intense beam of light through a process called stimulated emission. It stands for Light Amplification by Stimulated Emission of Radiation.
A laser works by stimulating atoms or molecules to release photons of light. These photons are then amplified as they bounce back and forth between mirrors inside the laser until they are released as a coherent and focused beam of light.
The main difference between a laser and a regular light source is the coherence and intensity of the light produced. Unlike regular light sources, a laser produces a single wavelength of light that is in phase and has a specific direction, making it much more powerful and precise.
Lasers have a wide range of applications in various fields such as medicine, communication, industry, and research. Some common uses of lasers include laser cutting, laser printing, laser eye surgery, laser communication, and laser spectroscopy.
Lasers can be harmful if not used properly. They can cause eye damage and skin burns if the beam is directed at a person. It is important to follow safety guidelines and wear protective gear when working with lasers.
