Interaction Between Pulsed Laser and Materials

“…where, E is the amplitude, c the speed of light, 0  the pulse center frequency, 0 n the linear refractive index, 2  the group velocity dispersion, 3  third-order dispersion constant, 4  fourth-order dispersion constant,  the loss coefficient. The first term describes the diffraction and the second, third and fourth terms are material dispersion terms.…”

“…The deposition of laser energy will produce a series of effects, such as temperature rise, gasification and ionization. The physical processes of interactions between lasers and matters can be grouped into linear and nonlinear responses of materials to laser pulses, namely thermal effects, nonlinear interactions, laser plasma effects and so forth [2,3] . This chapter aims at analyzing the abovementioned major effects due to laser irradiation.…”

Modeling Laser Effects on the Final Optics in Simulated IFE Environments

“…For example, deformation patterns formed on Si surfaces depend on the laser field orientation in relation to crystallographic axes (Banishev et al, 1992;Young et al, 1983b;Emel'yanov, 1992). This effect is of practical importance, since the corresponding defect accumulation induces a local decrease in the melting temperature, and can also influence the Laser Induced Damage threshold (LIDT) (Wood, 1986;Bennett, Guenther, Kozlowski, Newnam and Soileau, 1995).…”
