Abstract

Control over the parameters of a laser beam such as intensity and phase provides an important basis of modern photonics. Established control schemes, however, cover only a limited parameter range. We employ intense ultrasound fields in ambient air, enabling control of laser light in extreme parameter regimes. We acousto-optically modulate ultrashort pulses at 1030 nm with a peak power of 20 GW efficiently (⪆ 50%) in ambient air. Further, we show excellent beam profile conservation and separability of diffracted and transmitted beams. Finally, our approaches show that light control can prospectively be translated from solid-state media to the gas phase by means of intense ultrasound, considerably widening the scope of established light control methods.
