Abstract

We propose using high power, high brightness optically pumped vertical-external-cavity semiconductor lasers (VECSELs) as sources to build a partially coherent beam for laser communications applications. VECSELs are compact wavelength tunable, multi-Watt sources emitting light in a near TEM 00 mode. Our theory suggests that the scintillation index at a remote receiver can be significantly reduced by filling the transmitter aperture with an array of beams. An experiment will be reported on that confirms the theory predictions and demonstrates further that the reduction in scintillation index carried through to case of strong turbulence where our perturbation theory fails.
