Interference of two or more overlapping coherent laser beams leads to a spatially periodic
intensity modulation. Placing a material surface at this position and applying a sufficiently …

Surface treatment of metals and other materials is studied using sub-picosecond laser
pulses at 248 nm. The advantage of the combination of femtosecond pulse durations with …

The optics and processing apparatus for excimer laser microprocessing generally consists
of a beam shaping optics (homogenizer) and mask projection optics. The function of …

Femtosecond laser ablation occurs on timescales faster than the thermalization of the
excited electrons and the lattice in solid materials. The ultrafast deposition of energy …

Excimer laser ablation of common polymers is introduced and multipulse high aspect (up to
600) ratio microdrilling (diam. 25 μm) is explained. Mechanisms of material removal include …

Six years after the first commercial excimer lasers had found their way into research
laboratories, in 1982 Srinivasan and co-workers reported their discovery of the laser …

Over the last years a revolution has occurred in our ability to produce high power and
extremely high intensity pulses using more and more compact laser systems. The key …
