Laser spectroscopy is used to detect the composition and concentration of a material by analysing the spectrum produced when it interacts with light.
Laser spectroscopy techniques include Laser Absorption, Frequency Comb, Raman, Photoacoustic, and Ultra-fast, which differ according to the coherence, linewidth, wavelength and power of the laser light and the sample material.
Main application fields are:
- Monitoring of trace gases and water pollutants for the environment.
- Precise and rapid material analysis for applications in biology, medicine, and life sciences.
- Detection of explosives and drugs for security applications.
- Hyperspectral imaging for process monitoring and quality control in industry.
- Lock-in amplifiers, optical spectral analysers, oscilloscopes, monochromators, diffraction gratings, photodetectors.
