The transfer of energy to the hydrocarbon molecules is localized to less than 1 nm, which is ideal for high-resolution detection. See Y. Harada, S. Masuda, H. Ozaki, Chem. Rev. 97, 1897 (1997), and references therein.

J = +1 transition. These laser polarizations reduced the complex, multilevel state structure to the simplified level structure described in this report. In our calculations, we ignore the role of atoms returning to a different magnetic substate of the J = 2 manifold, as these atoms have a small effect on the spatial distributions produced.

note
-
Because of the diffraction of the laser beam from the edge of the substrate and experimental misalignments, the standing wave must suffer some imperfection immediately above the substrate. The extent of the clipping and the distance from the front edge of the substrate to the mirror are sufficiently small that we can neglect these contributions to the free flight experienced by the atoms.

The widths calculated numerically for the actual atom-laser potential agreed with the analytic predictions for these low well states, justifying the use of the SHO approximation in this regime.

2 half width) of 320 μm, power of 7.5 mW, and detuning of 18.5 MHz. During this long exposure, the temperature of the mount holding the substrate and the mirror used to generate the standing wave was stabilized to ±30 mK to ensure that the substrate did not move relative to the nodes of the standing wave. The sample mounting system was affixed rigidly inside the vacuum system and was designed for a high degree of passive mechanical stability.

note

The substrate was exposed for 5 hours to a beam of Ar* patterned by a standing laser field with a waist of 180 μm, power of 2.25 mW, and detuning of 28 MHz. The deposited carbonaceous material was used as a mask to protect against an aqueous 1% HF etch that removed the native oxide layer. A subsequent 70°C alcoholic KOH solution was used to transfer the pattern into the underlying silicon substrate.

In a demonstration of this potential for arbitrary pattern formation, the optical diffraction pattern formed by quenching light diffracting through a 10-μm-wide slit was used to pattern an Ar* beam [K. K. Berggren, thesis, Harvard University (1997)].
