Researchers at the Vienna University of Technology have developed a way to produce laser frequency combs simpler and more robust than before. This enables chemical analyzes in the smallest of spaces.
Lasers can be used, for example, to measure molecules in gases.

An ordinary laser has only one color whose photons have the same wavelength. In a frequency comb, the light, on the other hand, consists of many different frequencies (more…)
