Abstract
A laser tube for a laser generator used in a laser machining tool is formed by a plurality of disks laminated together to form an integral unit. The disks have a main hole for the passage of laser gas and at least one sub-hole for a sub-flow of laser gas. The sub-hole of each disk is connected with the respective main hole of the disk by a gas injection channel through which laser gas is injected into the main hole at a plurality of longitudinal positions in the laser tube to provide a homogeneous laser gas velocity distribution in the laser tube.
