Abstract

The properties of the depletion zone at a finite-size phototrap in two dimensions were studied by analyzing the concentration profile of the diffusing particles through the θ distance measure. The universality of this measure, as well as an early-time-short-distance behavior resulting from the finite disklike shape of the trap were confirmed. Comparison with theoretical and numerical results allowed to attribute a trapping strength parameter to the laser power used in the photobleaching experiment.
