Lasers are devices that produce highly focused beams of light through a process called stimulated emission, where excited atoms or molecules release photons in a coherent manner. This technology has applications across various fields, relying on the principles of absorption and emission of light, and the interaction of these processes within atomic lattices and optical lattices to achieve desired outcomes. The coherence and monochromatic nature of laser light make it valuable for precision tasks, such as cutting, measuring, and medical procedures.
