Determining the Stable Injection Locking of a Fabry-Pérot Laser by Observing the RF Spectral Components Generated by a Low-Reflectivity External Cavity

Photonics, 2021
A novel approach to monitoring the laser injection-locking (IL) state is proposed and verified using the side-mode suppression ratio (SMSR). In a photonics experiment for laser IL, an optical spectrum analyzer with the conventional criterion of a 35-dB ...

Semiconductor Laser Linewidth Theory Revisited [PDF]

, 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.

Contribution to Excitonic Linewidth from Free Carrier–Exciton Scattering in Layered Materials: The Example of hBN

Applied Sciences, 2022
Scattering of excitons by free carriers is a phenomenon, which is especially important when considering moderately to heavily doped semiconductors in low-temperature experiments, where the interaction of excitons with acoustic and optical phonons is ...

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 ...

The Variation of the Linewidths and Amplitudes of Sub-Doppler Resonances of 87Rb D2 Line with Laser Beam Intensity

Sakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2022
The sub-Doppler resonances linewidths and amplitudes depend on the laser beam intensity. The effect of laser beam intensity on the resonance linewidths and amplitudes obtained from different energy transitions of atoms varies from resonance to resonance.
