Femtika 3D Femtosecond Laser Manufacturing Systems with Bessel + Gaussian Beam

Femtika, a femtosecond laser processing company based in Lithuania, utilizes Multiphoton Polymerization (MPP)—a technology capable of producing arbitrarily shaped polymer structures with micron-level resolution. The process begins by dispensing a polymer material mixed with a photoinitiator onto a glass substrate, followed by pre-baking to prepare the photoresist sample. Next, laser direct writing is employed to fabricate 3D microstructures. Due to the photopolymerization process, the polymer solidifies at the precise locations within the droplet that are exposed to laser radiation. Finally, the microstructure is developed by immersing it in an organic solvent to remove the unpolymerized photoresist.
Thanks to its exceptional ability to produce complex and precise structures, MPP has become a popular choice for the fabrication of microelectronic devices. Its highly focused light source also enables the easy creation of intricate 3D geometries.
