Optical frequency combs based on femtosecond lasers have become invaluable tools in optical metrology and spectroscopy due to their unique ability to phase-coherently, linking the microwave and optical frequency domains. Combs based on lasers with 1 GHz repetition rate provide a unique combination of large mode spacing and high power coherent super-continuum generation.
Discover how gemstone analysts, industry regulators and law enforcement are using spectroscopy to distinguish genuine from artificial gemstones such as rubies and diamonds.
Ultra-short laser pulses are increasingly interesting to researchers in many different fields of work due to the inverse relationship between the spectral bandwidth emitted from the laser and its pulse duration. For many applications the need to stabilise the carrier envelope offset at these short pulse durations is an added indispensable requisite. One such application is the use of CEP stabilised pulses in high harmonic generation (HHG).
In this white paper, written by Edinburgh Instruments, learn how fluorescence spectroscopy - a fast and simple, minimally invasive and non-destructive technique - is used in the analysis of wine.
The paper discusses the methods and materials used when analysing two white wine samples, and shares the results of the analysis via clear and easy to read graphic illustrations.
