Laser spectroscopy is a technique that uses lasers to analyze the properties of materials. By shining a focused beam of light on a sample, scientists can observe how the light interacts with the material. This interaction provides valuable information about the sample's composition, structure, and other characteristics. The method is highly sensitive and can detect even trace amounts of substances. Laser spectroscopy is widely used in various fields, including chemistry, environmental science, and medicine, to identify compounds and study their behavior under different conditions.
