Fundamentals of Laser Spectroscopy III. Absorption and Reflection Spectroscopy.

Absorption / Transmission / Reflection Spectroscopy

Ultraviolet Visible Near-Infra red (UV-Vis-NIR) spectroscopy is useful to characterize the absorption, transmission, and reflectivity of a variety of technologically important materials, such as pigments, coatings, windows, and filters. This more qualitative application usually requires recording at least a portion of the spectrum for characterization of the optical or electronic properties of ...

Introduction Absorption spectroscopy is one of the oldest scientific methods for studying atomic and molecular structure. It is also one of the most powerful research tools for providing information about the world around us. One important application is ultrasensitive trace gas analysis, which is used in many area...

Tunable Diode Laser Absorption Spectroscopy of Oxygen

Femtosecond laser Fourier transform absorption spectroscopy.

A femtosecond mode-locked laser is used for what is believed to be the first time as a broadband infrared source for high-resolution Fourier transform absorption spectroscopy. A demonstration is made with a Cr(4+):YAG laser. The entire nu(1)+nu(3) vibration-rotation band region of acetylene, observed after passing through a single-pass 80-cm-long cell, is simultaneously recorded between 1480 an...
