Laser linewidths: tutorial [PDF]

open access: yesJournal 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).

Semiconductor Laser Linewidth Theory Revisited [PDF]

open access: yesApplied 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.

Effects of Linewidth Broadening Method on Recoil of Sodium Laser Guide Star

open access: yesAtmosphere, 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 ...

A Compact Self-Injection-Locked Narrow-Linewidth Diode Laser with Narrowband Dielectric Filter

open access: yesApplied Sciences, 2023
The self-injection-locked diode laser can significantly reduce the linewidth down to a sub-100 kHz level but requires optical filtering that is much narrower than the laser cavity linewidth.
