摘要

The diode laser stack comprises multiple laser-bar chips (1), which are arranged one above the other. The laser-bar chips have multiple emission zones, which are arranged parallel to each other. The width of the each emission zone is between 25 to 400 micrometers and the distance between the emission zones is 50 to 200 micrometers. The laser-bar chips are connected with a driver for periodic stimulation of the emission zones with a pulse-duty factor less than or equal to thirty percent. Independent claims are also included for the following: (1) a system with two or more diode laser stack (2) a method for generating laser radiation with a diode laser stack.
