| Abstract: |
| we report on the ability of the Multi-photon absorption (MPA) to build 3D polymeric structures with nano resolution and arbitrary dimension. 100 fs laser pulses were utilized for structuring. Different parameters such as laser power (laser pulse energy) and scanning speed were optimized to build qualitative structures. Using a medium numerical aperture (NA=0.85) microscope objective resolution of 300 nm was achieved. |
