In 1960, American physicist Theodore Maiman successfully demonstrated the first laser, a groundbreaking innovation in scientific technology. The laser, which stands for Light Amplification by Stimulated Emission of Radiation, emits coherent light at a single wavelength. This innovation significantly impacted numerous fields such as medicine, communications, and manufacturing. Its precision and versatility revolutionized practices like surgery and optical fiber communications, ushering in a new era of technological advancement.
