note = {Indium is a technologically interesting element in the semicoductor and opto-electronics industry.
Instead of other usually applied methods, we try to fabricate nano-structures of indium with atom lithography. The simulations show that the feature size of the structures is strongly dependent of the divergence of the indium atomic beam. Thus laser cooling is applied for transverse collimation. For laser cooling of indium, two wavelengths, i.e., 410nm and 451nm, of laser light are used. Light at 410nm is accessed by GaN diode lasers, while light at 451nm is generated by frequency-doubling a Ti-Sa laser emmiting at 902nm. The laser frequnecies are stabilized on the atomic resonance lines with the spectroscopic methods. We observed the optical manipulation of the indium atomic beam with laser light at both wavelengths and even one wavelength at 410nm.
The possible mechanisms are also discussed in the thesis.},
