Effect of laser intensity fluctuations on laser linewidth
Physical Review A, 1993We study the linewidth of a one-photon laser through the approach of the two-time correlation function. Our numerical calculations cover the regions of below, near, and above threshold. Well below threshold, the laser linewidth decreases linearly with increasing linear gain.

Linewidth of GaInAsSb diode lasers
SPIE Proceedings, 1992The linewidth of GaInAsSb diode lasers operating at 1.8-2.4 micron has been measured using gas absorption line as a frequency discriminator. The linewidth of the lasers varied from 3 to 60 MHz, could alter at least by an order of magnitude, and decrease as the temperature decreases and emission power increases. The results show that GaInAsSb lasers are

Linewidth of CaSbInAs diode lasers
SPIE Proceedings, 1992In all high resolution applications the quality of a diode laser as a source of coherent light is quite essential. For high resolution spectroscopy, the question is how much the recorded absorption line is broadened and what are its shape distortions due to the diode laser frequency fluctuations.

Classical theory of laser linewidth
Optical and Quantum Electronics, 1996The classical theory of light fluctuations rests on the intuitive concept that jumps between atomic states occur at independent times when the optical field has a prescribed value. The statistical properties of phase-noise sources are obtained in the present paper by applying this principle to detuned atoms.

Spectral Linewidth of Semiconductor Lasers
1986The semiconductor diode laser (SL) has a number of properties that make it a desirable light source for spectroscopy. Aside from the advantages in size, cost and complexity, SL’s cover a broad spectral range and may easily be modulated at rates up to several gigahertz. However, coherence remains an issue in many applications.

Natural linewidth of anisotropic lasers
Optical and Quantum Electronics, 1986The natural linewidth of lasers is shown to be enhanced with respect to the value predicted by the Schawlow-Townes formula when the gain is high and inhomogeneous in transverse or longitudinal directions. A general formula for the linewidth enhancement is derived from first principles: Maxwell's equations and the fluctuation-dissipation theorem, for ...
