Ultimate Stability of Methane-Stabilized Lasers
Japanese Journal of Applied Physics, 1973Random frequency fluctuations of the 3.39 µm He-Ne lasers stabilized on an absorption line of methane are theoretically investigated. The minimum detectable frequency deviations are calculated for the method of linear absorption in an external cell and for the method of saturated absorption in an internal cell, and compared with each other.

An introduction to stabilized lasers
Contemporary Physics, 1989Abstract This paper provides an introduction to methods for stabilizing continuous-wave single-mode lasers and discusses the fundamental limits on the maximum stability achievable. Both passive and active methods are described, the latter being treated by separating the problems of error discrimination and error correction.

Laser Wavelength Stabilization
2018Figure 7.1 depicts the scheme of a feedback loop that underlies many servo systems used to stabilize the frequency of optical lasers. This chapter presents examples of the ways this stabilization can be realized. Basically, the scheme consists of a wavelength comparator that generates the error signal for the feedback loop by processing a reference ...

Stabilization of Semiconductor Lasers
2012Chaos and instabilities are not only the effects in semiconductor lasers with external perturbations. Semiconductor lasers are also strongly stabilized by external perturbations under appropriate parameter conditions. Optical injection from a different laser is a typical example of laser stabilizations.
