Spectroscopy is the study of how light interacts with matter, providing insights into the composition, structure, and properties of substances. This technique is pivotal in understanding various phenomena, such as population inversion in laser systems and the linewidths of laser emissions. Spectroscopy also plays a crucial role in applications like gas and dye lasers, where it helps analyze energy levels and transitions that lead to laser action.
