Abstract

A magneto-optical trap recently built in our laboratory is described. The principles of operation and construction details are given together with the description of the lasers used in the set-up.

We present details for construction and the operation of a mirror magneto-optical trap for cooling and trapping rubidium atoms. For trap operation, only four input laser beams are needed in contrast to the normal six for a standard trap. In excess of 108 atoms have been trapped with this arrangement, with the atomic ensemble only ∼1mm from the surface of a reflective mirror. This trap is highly suited to studies of magnetic guiding and magnetic manipulation of cold atomic ensembles.

Magneto-Optical Trap Optimization

T.J.G. Verboven

To maximize the number of Rubidium atoms loaded into a magneto-optical trap, we investigate the absorption spectrum to determine the detuning of the laser to load as much atoms as possible. We also vary the magnetic field strength and laser intensities to determine the settings for which the trap is loaded the fastest.

Magneto Optical Trapping of Rb 87

C. Awe

Magneto optical traps brilliantly combine semi-classical optics with modern physics. By carefully controlling the polarization and frequency of laser beams, it is possible to trap and cool atoms down to the millikelvin range at a relatively low cost. This has opened previously inaccessible physical domains to enterprising physicists all around the world, and is responsible for some of the most interesting experiments being conducted in AMO sciences today. We attempted to employ magneto optical trapping techniques to generate a sample of Rubidium 87 atoms for use in the development of multidimensional Fourier transform spectroscopy with comb lasers. My work entailed the construction and characterization of two external cavity diode lasers (ECDLs), as well as the assembly of a MOT system, which is as of 04/07/2015 not operational. Future work will focus on debugging the system.
