Abstract: In laser processing of surfaces, typically to impart some texture or to drill shallow holes, it is necessary to correlate pulse properties (wavelength, power, beam radius and quality, duration) and material properties (reflectivity, melting temperature, conductivity, diffusivity) mainly with the depth of the formed crater. Crater shape is assumed to be paraboloidal and its maximum diameter is assumed to be uniquely related to its depth. An empirical and an analytical model are suggested to this end. The former entails construction of Artificial Neural Networks from experimental measurements, whilst the latter entails modification of established models from literature. Both types of models are exemplified in this paper drawing on data from available literature.

Abstract: The semiconductors have conductions ranged between the conductors and nonconductors. Conduction makes the semiconductors one of the most important materials for electric applications. Therefore, with the receiving pulses from cathode in different geometries such as Cartesian, cylindrical and spherical the most commonly used pulse is the pulse created by the detector with cubic geometry.
