Lasers are used in various fields, including medicine, manufacturing, and telecommunications. In medicine, they assist in procedures like laser eye surgery and skin treatments, providing precision and minimal recovery time. In manufacturing, lasers cut and engrave materials, enhancing efficiency and accuracy in production processes. In telecommunications, lasers transmit data over long distances through fiber optic cables, enabling high-speed internet and communication. Additionally, lasers play a role in scientific research, such as spectroscopy, where they help analyze materials by measuring light absorption and emission. Their versatility makes lasers essential tools in modern technology.
