LASER RADIATION SOURCE FOR PRODUCING A COHERENT AND ENTIRE LASER RADIATION FIELD

摘要

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.
