Laser Spectroscopy
Laser spectroscopy is a technique that uses lasers to analyze the properties of materials by studying how they interact with light. When a laser beam is directed at a sample, it can excite the atoms or molecules, causing them to emit or absorb light at specific wavelengths. This information helps scientists identify the composition and structure of the material.
This method is widely used in various fields, including chemistry, physics, and environmental science. By employing different types of lasers and detection methods, researchers can gain insights into molecular dynamics, chemical reactions, and even pollutant levels in the atmosphere.
