Description
The speckle pattern produced when a laser illuminates a random medium can be used to uniquely identify the wavelength of the illuminating source. By performing appropriate multivariate analysis of the speckle pattern produced by propagation through a metre-long step-index multi-mode optical fibre, we achieve a femtometre-precision wavemeter. This can also be used to stabilize the frequency of the laser at arbitrary frequency and thus has exciting potential applications in quantum technology experiments with cold atoms.| Period | 31 Jan 2018 |
