Abstract: A laser diode arrangement has a joint electrically insulating substrate, a plurality of laser diodes arranged in the joint electrically insulated substrate, conductor structures provided on the substrate so that, the laser diodes are connected with one another through the conductor structures, and a joint control of the laser diodes.

Abstract: The invention concerns an apparatus and a system for the transfer of optical data between satellites, which encompasses a laser oscillator (10) for generating an optical signal, a modulator (11) for modulating the optical signal with data information, and an amplifier assemblage, a collimator assemblage, and a transmission device for transfer of the signals. Provision is made for a preamplifier (12) to be connected to a power divider section (13) downstream from which is a parallel circuit of at least two phase shifters (14) and main amplifiers (15), respectively connected in series, for amplification and adjustment of the optical signals; and for the main amplifiers (15) to be connected, via a bundle (16) of optical waveguides corresponding to the number of series circuit(s), to the corresponding number of collimators (17).
