TwoPhotonPolymerization. Atomic Scale Design : Two-Photon Polymerization. The history of the development of the femtosecond (10-15 sec) laser systems is intense and exciting one.
Due to the extremely short duration of the pulse, the peak power of modern commercially available laser can exceed 200 gigawatt. In comparison, the total power of power stations of Germany, including solar power plants, and wind power stations are expected to approach 120 GW by the year 2010. Application of femtosecond pulses allows the introduction of laser energy with unprecedented precision in space and time. By applying the light source that has the same timescale as molecular vibrations, one could observe and even control the outcome of chemical and biological reactions in a real time. Doc-712.
