Analysis of Cr Atoms Three-Dimensional Deposition Characteristics
The semi-classical model is used to simulate the three-dimensional trajectory and deposition distribution of the chromium atoms in the Gaussian laser standing wave field using the Runge-Kutta method, and then the three-dimensional deposition stripes are also given, besides, the effects of atomic beam divergence, chromatic aberration and spherical aberration on deposition structure are also analyzed.
Nanostructure fabrication by reactive-ion etching of laser-focused chromium on silicon

6 plasma. We show that the result can be an array of parallel wires as narrow as 68 nm or an array of parallel Si trenches as narrow as 85 nm. The laser-focused deposition process is inherently parallel, so a large area is patterned simultaneously with an accurate periodicity of 212.78 nm. This method represents a novel way to make large, coherent arrays of sub-100 nm-size structures.

Quantum wave function simulation of the resonance fluorescence spectrum from one-dimensional optical molasses.
Using recently developed quantum wave function techniques, we have performed a simulation of 85 Rb atoms in a one-dimensional optical molasses, formed from counterpropagating laser beams with orthogonal linear polarizations. Both internal and external degrees of freedom are treated quantum mechanically in one dimension and the spectrum of resonance fluorescence is calculated and compared to recent experiments. Excellent agreement is obtained for the spectrum and additional insight is gained into the experimental evidence for quantized motion in the optical potentials
