We herein report a simultaneous frequency stabilization of two 780-nm external cavity diode lasers using a precision wavelength meter (WLM). The laser lock performance is characterized by the Allan deviation measurement in which we find σy=10−12 at an averaging time of 1000 s. We also obtain spectral profiles through a heterodyne spectroscopy, identifying the contribution of white and flicker noises to the laser linewidth. The frequency drift of the WLM is measured to be about 2.0(4) MHz over 36 h. Utilizing the two lasers as a cooling and repumping field, we demonstrate a magneto-optical trap of 87Rb atoms near a high-finesse optical cavity. Our laser stabilization technique operates at broad wavelength range without a radio frequency element.

We propose a novel scheme to generate nanoscale optical trap for cold atoms near the tapered Ag nanotip, in which we take a microdisk cavity near the nanoscale trap and form a nanoscale solid-state system to realize the loading of the isolated cold atoms. We calculate the field distribution by the FDTD method near the nanotip, and discuss the intensity, the optical potential and van der Waals potential as well as the dipole force for 87Rb atoms. We find that the total potential and dipole force can form an attracting nanoscale trap for cold atoms with red-detuned field and it can realize the effective trapping and manipulation of the isolated atoms, which can enable efficient fluorescence photon collection and strong coupling in the coupled optical fiber.
