Laser Based Micromachining

Laser-based micromachining processes have been applied to date only on a relatively small scale for manufacturing chemical microdevices (27). This will probably change relatively soon, since rapid prototyping will become more and more important for developing novel microreaction devices. 

Laser-Based Micromachining, Fig. 2 Schematic of laser micromachining system for rapid prototyped three-dimensional channel netwoiks using a femtosecond laser. The femtosecond laser provides intensities that overcome the ablation threshold at the tightly focused heam waist...
