Diode laser arrangement, e.g. for pumping solid state lasers, has series diode lasers with normally high impedance bypass elements for bridging diode lasers with high impedance defects

摘要

The diode laser arrangement has a number of diode lasers (2) electrically in series and each electrically in parallel with a bypass arrangement (4) that is of high impedance in normal operation and that can bridge the associated diode laser in low impedance manner in the vent of a high impedance defect of the relevant diode laser.
