Ultra short laser pulses are tightly focused into a photosensitive medium at 780 nm wavelength.At this wavelength the exposed material is completely transparent. However, if the intensity of the laser beam exceeds a certain threshold, a nonlinear two-photon absorption process takes place. This happens only in the very focal volume of the laser beam. Thus, the material is only chemically and/or physically modified within this small focal volume, which can be much smaller than the wavelength of light used for the illumination. Computer controlled translation of the sample with respect to the spatially fixed focus position in combination with laser control allows the fabrication of almost arbitrarily complex 3D structures in the photosensitive material. A specially developed, user-friendly software coordinates the movement of the sample and provides you with all the freedom you need in designing your 3D structures - even on the submicrometer scale: May your application be complex photonic structures like e.g. photonic crystals, resonators or microcircuitry, microfluidic devices or structures for cell growth studies or stem cell differentiation – Nanoscribe’s ‘Photonic Professional’ is your choice.
