Feedback control of ultra-high-Q microcavities: application to micro-Raman lasers and microparametric oscillators [PDF]
, 2005 We demonstrate locking of an on-chip, high-Q toroidal-cavity to a pump laser using two, distinct methods: coupled power stabilization and wavelength locking of pump laser to the microcavity.

SEMICONDUCTOR FREQUENCY STANDARD BASED ON P(16) SPECTRAL LINE OF ACETYLENE ISOTOPE WITH TEMPERATURE STABILIZATION BY PHASE MODULATION [PDF]
Научно-технический вестник информационных технологий, механики и оптики, 2018 This paper reviews the method of semiconductor laser diode frequency stabilization by phase modulation. Also parameters are identified that affect the quality of stabilization and the estimation of Allan deviation is obtained.

Two-color stabilization of atomic hydrogen in circularly polarized laser fields [PDF]
, 2002 Dynamic stabilization of atomic hydrogen against ionization in high-frequency single- and two-color, circularly polarized laser pulses is observed by numerically solving the three-dimensional, time-dependent Schr\"odinger equation.

Stability of Continuously Pumped Atom Lasers [PDF]
Physical Review Letters, 2002 A multimode model of a continuously pumped atom laser is shown to be unstable below a critical value of the scattering length. Above the critical scattering length, the atom laser reaches a steady state, the stability of which increases with pumping. Below this limit the laser does not reach a steady state. This instability results from the competition

Medium-power stabilized laser diode
SPIE Proceedings, 1998 Power stabilized DL's represent today convenient sources for radiometric applications, as transfer laboratory standards. Stability measurements were carried out and reported by other authors for different time intervals, but only for low optical power levels (max. 16 mW).

Narrow linewidth single laser source system for onboard atom interferometry [PDF]
, 2014 A compact and robust laser system for atom interferometry based on a frequency-doubled telecom laser is presented. Thanks to an original stabilization architecture on a saturated absorption setup, we obtain a frequency-agile laser system allowing fast ...
