Optics With Cold Atoms
Abstract
For production of novel non-linear excitations in Bose-Einstein condensates, we have enhanced the efficiency and stability of our Bose-Einstein-condensate setup by upgrading one of our primary laser pumps with a modem Verdi V-10 laser system. Furthermore, we are developing the world's most sensitive single-cold-atom detector based on free-standing carbon nanotubes to ionize neutral atoms. We have generated the facilities necessary for nanotube growth and detailed characterization with the purchase of a Raman microscope. And to test the novel atom sensor, we have built a moving-molasses magneto-optical trap in a geometry tailor-suited to the nanotube detector geometry, involving construction of a highly stable laser source and electro-magnets, with associated power supplies and control circuitry. In addition, we have applied the DURIP support to produce a Continuous source of cold atoms with the highest flux ever obtained (by 1-2 orders of magnitude). This has involved significant upgrades to the optics-table Set-up, control electronics and data acquisition system, acquisition of a Fabry-Perot spectrum analyzer, purchase of acousto-optic deflectors with corresponding RF frequency drivers, and custom-building of electronic frequency-belting systems. Characterization of the generated, intense atom beam required similar infrastructure investments, including an acquisition and control computer and electronics with precise timing.
