Optimum parameters for sideband cooling of a 40Ca+ ion

Abstract

Optimum conditions for sideband cooling of 40Ca+ are numerically analyzed and appropriate parameters are evaluated. The dependence of optimum parameters for sideband cooling on the realistic experimental conditions, such as laser linewidth or heating rate, is investigated. For experimental verification of the analysis, a single 40Ca+ is sideband-cooled using parameters based on the analysis, and the achieved average oscillation quantum numbers are evaluated. As a result, a good agreement between the experimental value and numerical analysis is obtained.
