Laser phase noise reduction for industrial interferometric applications

Applied Optics, 2004
Laser ultrasound is a technique used for the ultrasonic inspection of composites during manufacturing of advanced jet fighters. With this technique laser interferometry is used to detect ultrasonic displacements generated by a laser. In theory, the signal-to-noise ratio is proportional to the square root of the collected detection light.

Theory of Interferometric Analysis of Laser Phase Noise*

Journal of the Optical Society of America, 1966
The line width of a well-stabilized laser operating far above threshold is determined by random fluctuations of the phase. This paper discusses several types of experiments which can give information about the details of this phase random process. In order to study the laser phase noise experimentally the laser signal (containing phase noise only) must

Reducing the phase noise in diode lasers

Optics Letters, 2019
Diode lasers are widely used in atomic physics given their narrow linewidth and wavelength tunability. Nevertheless, although they present low noise for their intensity, excessive noise in the phase limits their application in quantum optics. Looking for reduction of this phase noise, we built and characterized a ring laser, using a semiconductor ...

Single-mode diode laser phase noise

Applied Physics Letters, 1981
Measurements have been made of the phase noise of a single-mode diode laser in an unbalanced Michelson interferometer, as a function of optical path difference. The noise increased linearly with increasing optical path difference. The origin of the phase noise is discussed.
