In this paper, a technique for modifying the laser power spectrum by use of an acousto-optic modulator is described, and the theory of the power spectrum resulting from frequency modulation by Gaussian noise is reviewed.Abstract:
A technique for modifying the laser power spectrum by use of an acousto-optic modulator is described. The theory of the power spectrum resulting from frequency modulation by Gaussian noise is reviewed, and several examples of broadened laser power spectra are presented.read more

Simple approach to the relation between laser frequency noise and laser line shape
TL;DR: A simple approach to this relation with an approximate formula for evaluation of the laser linewidth that can be applied to arbitrary noise spectral densities is presented.

Quantum cascade lasers in chemical physics
Robert F. Curl,Federico Capasso,Claire F. Gmachl,Anatoliy A. Kosterev,Barry McManus,Rafal Lewicki,Michael Pusharsky,Gerard Wysocki,Frank K. Tittel +8 more
TL;DR: In the short space of 15 years since their first demonstration, quantum cascade lasers have become the most useful sources of tunable mid-infrared laser radiation as discussed by the authors, and the potential application of quantum cascade laser in other areas of chemical physics such as research on helium droplets, in population pumping and in matrix isolation infrared photochemistry.

Quantum cascade lasers: a versatile source for precise measurements in the mid/far-infrared range
TL;DR: In this article, the authors provide an overview of recent developments of quantum cascade lasers (QCLs), from the mid-infrared (mid-IR) to the far-IR (THz) range, with a special focus on their metrological-grade applications in a number of fields.

Low-noise fiber-laser frequency combs (Invited)
TL;DR: In this paper, the experimental and theoretical aspects of a low-noise fiber-laser frequency comb were discussed, including the experimental configuration and the major contributions to the frequency noise and linewidth of the individual comb modes.

Laser stabilization at the millihertz level
Ch. Salomon,D. Hils,John L. Hall +2 more
TL;DR: In this paper, it was shown that if any of these laser sources were optimally locked to a high-finesse Fabry-Perot cavity, it would be theoretically possible to obtain a laser linewidth in the millihertz domain.
