The body has a smooth outlet end through which the laser is configured entirely by laser cutting. The entry portion of the through passage preferably has a hemispherical end penetrated by the orifice. Manufacturing steps including laser cutting of the orifice or orifices and optional electrical discharge machining of the hemispherical end of the entry portion.
