Laser induced ionization of matter is important in many applications of laser matter interaction. In this paper, femtosecond laser interaction with weakly-ionized Helium plasmas is simulated using the lattice Boltzmann method (LBM). Ionization of Helium atoms as well as the loss of free electrons due to recombination is taken into account in the model. The electromagnetic fields of the laser beam and the plasma are solved by using the Finite-Differen...$28.00

Recent advances in the field of highly brilliant continuous wave fibre laser sources lead to an increase of intensity. These intensities were formerly reserved to short pulse laser sources with pulse durations of several nanoseconds. As a result of this combination of wavelength, intensity an...$28.00

Glass is a useful material. Recently, the utility of the inside processing of the glass with the laser came to be recognized. The glass is heterogeneous as processing materials with the laser. When heat occurred in the inside of the glass, the crack occurs in a random course, and a phenomenon is complicated. In addition, in the case of inside processing with the laser, the mechanism is very pec...$28.00

Presented at ICALEO 2008
An important challenge for all processes based on laser material removal is the control of the precision of the shape. This is so, because all methods are non-contact methods and the removal rate underlies certain influences depending on the exact processing conditions and material properties, making only limited prediction and control of the removal rate possible. In laser chemical machining the radiation locally initiates on a metal surface a thermochemi...$28.00
