Abstract

We study a scheme for state-insensitive trapping of neutral atoms by using light with two independent wavelengths. In particular, we describe the use of trapping and control lasers to minimize the variance of the potential experienced by a trapped Rb atom in ground and excited states. We present calculated values of wavelength pairs for which the $5 s$ and $5 p_{3 / 2}$ levels have the same ac Stark shifts in the presence of two laser fields.
