Conical and volumetric laser beams in laser technologies

摘要

Some optical schemes for the production of conical beams with high cone angle and a quasi-uniform axial distribution of the intensity have designed and a elaborated method of laser power delivery in heterogeneous stream are used for nanopowder production and SLC process modification. The new principles of laser pulse generation are elaborated and optical schemes for production of a volumetric laser beams convergent spherical and cylindrical have been designed. On the base of laser system developed and concept of quasitransparent first wall the reactor construction design intent has been proposed.
