Abstract

When atoms are laser cooled to below the single photon recoil limit, their deBroglie wavelengths become comparable to or larger than the wavelength of light used to cool them. To describe properly the physics in this regime, it is necessary to quantize the external (atomic momentum) degrees of freedom. We describe here several 1-d laser cooling experiments in this quantum regime with metastable helium atoms that demonstrate several novel features in subrecoil laser cooling.
