Diode laser configuration with a plurality of diode lasers that are electrically connected in series

摘要

A diode laser array has a plurality of electrically series-connected diode lasers. Each of the diode lasers has a bypass device that is electrically connected in parallel with the laser. The bypass is high-ohmic in normal operation and bypasses the diode laser with low resistance in the case of a diode laser diode defect, that would otherwise lead to high-ohmic interruption of the electric circuit. The bypass configuration is disposed on a cooling and contact element together with the diode laser.
