“…Also acoustooptical modulators [75,76], which shape the optical electric field by diffracting it on a modulated acoustic wave, can be used for this purpose [77], albeit with a low diffraction efficiency and hence low throughput. Micro mirror arrays [78], which consist of individually addressable small mirrors, have also been introduced for this purpose [79]. While these devices are probably the most efficient solution to the problem, they were not commercially available until recently, and could therefore not be employed in the experiments presented here.…”
