Using diode lasers for atomic physics

We present a review of the use of diode lasers in atomic physics with an extensive list of references. We discuss the relevant characteristics of diode lasers and explain how to purchase and use them. We also review the various techniques that have been used to control and narrow the spectral outputs of diode lasers. Finally we present a number of examples illustrating the use of diode lasers i...

Equilibrium capillary forces with atomic force microscopy.

We present measurements of equilibrium forces resulting from capillary condensation. The results give access to the ultralow interfacial tensions between the capillary bridge and the coexisting bulk phase. We demonstrate this with solutions of associative polymers and an aqueous mixture of gelatin and dextran, with interfacial tensions around 10 microN/m. The equilibrium nature of the capillary...

Atomic Samples in Resonators: Forces, Photons, Feedback

We analyze laser cooling of polarizable particles (classical light scatterers) using continuous dispersive position detection and active feedback with an optical resonator. We derive a simple expression for the cooling force, and show that its magnitude is proportional to the Rayleigh scattering rate into the detector. The velocity dependence of the force is determined exclusively by the freque...

Uncertainties in forces extracted from non-contact atomic force microscopy measurements by fitting of long-range background forces

In principle, non-contact atomic force microscopy (NC-AFM) now readily allows for the measurement of forces with sub-nanonewton precision on the atomic scale. In practice, however, the extraction of the often desired 'short-range' force from the experimental observable (frequency shift) is often far from trivial. In most cases there is a significant contribution to the total tip-sample force du...
