Lattice dynamics of iron chalcogenides: Raman scattering study [PDF]
Journal of the Serbian Chemical Society, 2017 The discovery of superconductivity in FeSe led to a new subclass of high-temperature superconductors – iron chalcogenides. Materials from this group exhibit variety of specific features, from superconductivity with relatively high critical temperatures ...

Semiconductor Laser Linewidth Theory Revisited [PDF]
Applied Sciences, 2021 More and more applications require semiconductor lasers distinguished not only by large modulation bandwidths or high output powers, but also by small spectral linewidths. The theoretical understanding of the root causes limiting the linewidth is therefore of great practical relevance.

Laser linewidths: tutorial [PDF]
Journal of the Optical Society of America B, 2021 In this tutorial, the physical origins and mathematical analyses of laser linewidths are reviewed. The semi-classical model is based on an equation for the light-mode amplitude that includes random source terms, one term for each process that affects the amplitude (stimulated and spontaneous emission, stimulated absorption, and facet and material loss).

Effects of Linewidth Broadening Method on Recoil of Sodium Laser Guide Star
Atmosphere, 2021 The linewidth broadening of the circular-polarized continuous wave laser mitigates the recoil effects of the sodium laser guide star very well. By choice of the optimal laser linewidth, the relations between the laser intensity and average spontaneous ...
