FIELD: liquid or gas jet formation methods to be used in mining, building and other industries.
SUBSTANCE: method involves using laser emission having ring cross-section as accompanying energy flow, wherein liquid and gas jet is inside the energy flow.
EFFECT: possibility of jet forming with accompanying energy flow so that the jet is non- turbulent along the full working jet length, increased jet density and possibility to retain axial dynamic pressure for the full free jet section due to jet isolation from ambient space.
