The results of studies of laser-jet materials processing technologies, as one of the promising methods for cutting a variety of products are shown. On the basis of current world developments are considered features profiling nozzles (transition region) for optimal formation of laser-jet flow. Optimal nozzle opening of the cavity, satisfying all the stated requirements have been created. Using a simulation program Mathcad propagation of the luminous flux in the nozzle cavity and in the free jet. Mathematical modeling of fluid flow through the nozzle into the cavity built software environment FlowVision was conducted. Research on the simulation installation and laser-jet complex LSK-400-5 was conducted. The diameter of the jet should be greater than the diameter of the laser ray by the amount of its decay.References
