In this thesis high pulse energy femtosecond laser machining station for periodic surface structuring will be presented. This machine was developed to provide possibility for surface texturing using several established patterning technologies such direct interference patterning, parallel patterning using array of focused laser beams, and self-organized surface patterning with single laser beam, or hybrid texturing using combination of these methods. Ultrashort high energy laser pulses are known to undergo distortions in optical materials or even air due to the non-linear effects. Therefore, characteristics of the laser pulse at the input and output of the interference system were investigated. Several applications of the machining station will be presented, including control of aluminum friction properties and fabrication of optical elements for THz radiation.
