Optical Pumping Optical pumping is a process used to excite atoms, ions, or molecules in a material to higher energy states using light or optical radiation. It is commonly employed in laser technology to create population inversion, a condition where more atoms or molecules reside in higher energy states than in lower energy states. Population inversion is a fundamental requirement for the operation of many types of lasers, including solid-state lasers, gas lasers, and semiconductor lasers.
By optically pumping a laser gain medium, such as a crystal, gas mixture, or semiconductor material, energy is transferred to the atoms or molecules, resulting in the emission of coherent light through stimulated emission processes. Optical pumping techniques play a crucial role in the generation of laser beams with specific wavelengths, powers, and properties for various scientific, industrial, and medical applications.
