Abstract: A laser radiation source is provided with an array of N individual slave laser diodes in a predetermined surface area. Adjustable power supply networks enable adjustment of the slave laser diodes relative to one another for operation in a stable manner. The slave power supply has a separate power supply network for each slave laser diode. Each of the power supply networks can be adjusted with respect to the current supplied to the respective slave laser diode during a certain operating period. This enables adjusting the slave laser diodes relative to one another. The power supply networks can be connected in parallel and supplied by a common source.

Abstract: In order to improve a laser radiation source comprising an array of N individual slave laser diodes in a predetermined surface area, a slave power supply for the slave laser diodes, a master laser diode for generating a master laser radiation, a master power supply for the master laser diode, an optical coupling device, with which the master laser radiation can be coupled into the individual slave laser diodes in order to operate them at the frequency of the master laser diode in a phase-locked manner, and an optical transformation device which combines the slave laser radiation of the individual slave laser diodes to form a coherent total laser radiation field with essentially plane wave fronts, in such a manner that it is possible as a result of the adjustability of the power supply networks to adjust the slave laser diodes relative to one another and thus operate them in a stable manner in relation to one another it is suggested that the slave power supply have a separate power supply network for each slav
