Laser diode component with numerous laser diodes in series, each with resistor in parallel, for use of large number of laser diodes in diode stacks

摘要

Laser diode component comprises numerous laser diodes (D1...D5) in series, each with resistor (R1...R5) in parallel. At least one laser diode is a diode stack and laser diodes have different capacities.Preferably each parallel resistor, at switching of laser diodes, limits, or suppresses voltage at laser diodes in blocking direction. Typically resistors are coupled in parallel as discrete components and may be integrated in laser diodes. Resistor dimensioning provides fading time of diode voltages corresponding to their switching time.
