Laser deposition of multiwalled titanium oxide microtubes

We propose approaches to producing micro- and nanostructured titanium oxide surfaces via exposure to cw laser radiation and repetitive laser pulses. By varying the experimental geometry (angle of incidence, substrate-target separation and other parameters), various structures can be obtained. Titanium oxide tubes grown in a nonuniform magnetic field are up to 1 μm in diameter and up to 500 μm in length. Such structures can be used in catalytic filtration and as multiwalled structures similar to superlattices.
