A narrow-linewidth external cavity quantum dot laser for high-resolution spectroscopy in the near-infrared and yellow spectral ranges
A. Yu. Nevsky, U. Bressel, Ch. Eisele +7
We demonstrate a diode laser system which is suitable for high-resolution spectroscopy in the 1200 nm and yellow spectral ranges. It is based on a two-facet quantum dot chip in a L…

A New Option for a Search for Alpha Variation: Narrow Transitions with Enhanced Sensitivity
S. G. Karshenboim, A. Yu. Nevsky, E. J. Angstmann +2
We consider several transitions between narrow lines that have an enhanced sensitivity to a possible variation of the fine structure constant, alpha. This enhancement may allow a s…
