A high-brightness diode laser bar system for industrial test

The objective of this project was to develop a high-brightness diode laser bar system to be used for industrial testing. Diode laser bars are very efficient and high power laser sources with the major drawback being the poor beam quality and thus the low brightness. In this project, newly developed techniques based on off-axis spectral beam combination will be employed to improve the beam quality to close to the diffraction limit. This will lead to record-high values for the brightness of the laser system.
