6 Most Common Types of Laser Spectroscopy Techniques

Laser spectroscopy is a powerful tool for analyzing the physical and chemical properties of matter. It involves the interaction of light with matter, which is then used to analyze the sample. Laser spectroscopy is used in a variety of fields, including physics, chemistry, biology, and medicine. In this article, we will discuss the six most common types of laser spectroscopy techniques.

1. Absorption spectroscopy

Absorption spectroscopy is a technique that measures the absorption of light by a sample. It is one of the most common types of laser spectroscopy techniques. In this technique, a laser beam of a specific wavelength is passed through the sample. The amount of light absorbed by the sample is measured and used to determine the properties of the sample. Absorption spectroscopy is used in a wide range of applications, including environmental monitoring, medical diagnostics, and materials analysis.

2. Fluorescence spectroscopy

Fluorescence spectroscopy is a technique that measures the emission of light by a sample. It is based on the principle of fluorescence, which is the emission of light by a molecule that has absorbed light. In this technique, a laser beam of a specific wavelength is used to excite the sample, which then emits light at a longer wavelength. Fluorescence spectroscopy is commonly used in biology, chemistry, and medical diagnostics.

3. Raman spectroscopy

Raman spectroscopy is a technique that measures the scattering of light by a sample. It is based on the Raman effect, which is the scattering of light by molecules that are excited by a laser beam. In this technique, a laser beam of a specific wavelength is passed through the
