Dynamical spatial light modulation in the ultraviolet spectral range

Abstract

Spatial light modulators enable arbitrary control of the intensity of optical light fields and facilitate a variety of applications in biology, astronomy and atomic, molecular and optical physics. For coherent light fields, holography, implemented through arbitrary phase modulation, represents a highly power-efficient technique to shape the intensity of light patterns. Here, we introduce and benchmark a novel spatial light modulator based on a piston micro-mirror array. In particular, we utilize the reflection-based device to demonstrate arbitrary beam shaping in the ultraviolet regime at a wavelength of 322 nm. We correct aberrations of the reflected wavefront and show that the modulator does not add detectable excess phase noise to the reflected light field. We utilize the intrinsically low latency of the architecture to demonstrate fast switching of arbitrary light patterns synchronized with short laser pulses at an update rate of 1 kHz. Finally, we outline how the modulator can act as an important component of a zone-based architecture for a neutral-atom quantum computer or simulator, including ultraviolet wavelengths.
