The taccor comb - high power frequency comb with 1 GHz mode spacing

By Albrecht Bartels and Matthias Beck of Laser Quantum
6 May 2016

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.

Creating ultra-short phase stabilised pulses for high harmonic generation (HHG)

By Thomas Binhammer, Laser Quantum
10 February 2016

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).

Fluorescence spectroscopy of wine

By Edinburgh Instruments
1 December 2015

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.

Gas Sensing using tunable mid-IR lasers and Photoacoustic spectroscopy (PAS)

By Cobolt AB
28 September 2015

White Paper Lead ImageAlthough the technique of Photo-Acoustic Spectroscopy (PAS) has been around for over a century, the method has been somewhat limited in sensitivity due to the microphone and laser technology. In recent years improvements have been made on both these fronts which mean that PAS is now viewed as an advanced method for very sensitive trace gas analysis and detection.
