Spectral phase, amplitude, and spatial modulation from ultraviolet to infrared with a reflective MEMS pulse shaper

Abstract

Abstract:We describe the performance of a reflective pulse-shaper based on a Micro-ElectroMechanical System (MEMS) linear mirror array. It represents a substantial upgrade of a preceding release [Opt. Lett. 35, 3102 (2010)] as it allows simultaneous piston and tilt mirror motion, allowing both phase-and binary amplitude-shaping with no wavelength restriction. Moreover, we show how the combination of in-axis and tilt movement can be used for active correction of spatial chirp.

Direct amplitude shaping of high harmonics in the extreme ultraviolet

“…Obviously, more sophisticated masks with multiple slits, adapted to the whole set of HHs, can be constructed and adapted to the purpose of future experiments. Very interestingly, tilt motion can be used not only for amplitude modulation but also for achieving k vector optimization [19] in multi-XUV wave mixing experiments such as those theoretically proposed by S. Mukamel [12].…”

“…In this work, we realized amplitude shaping by modifying the A q in a controlled way. The spectral phases ϕ(ω q ) can also be controlled by the present MEMS device, which provides both tilt and stroke capabilities [19], but a full spectral and temporal characterization would require a dedicated experimental setup different from the one presented here (see e.g. Ref.…”

“…Moreover, the MEMS device used in our experiment is able to provide simultaneously tilt and stroke motion [19] (see supplementary movie Media 4) such that phase shaping can be added to amplitude shaping. Using our device, one could simultaneously compensate the attochirp and imprint an arbitrary phase mask onto the isolated attosecond pulse, opening a vast field of applications in attoscience.…”

Discriminating Biomolecules with Coherent Control Strategies

“…Unlike previous developments using commercial wavefront correction devices, [8][9][10] our approach consists of tailoring a micromirror array for this specific application. [11] The 100-micromirrors contained within the device allow excellent reflectivity over the whole DUV-Vis-NIR (Al coating, Typ. 80-90%) and negligible wavefront distortion.…”

Design, simulation, fabrication, packaging, and characterization of a MEMS-based mirror array for femtosecond pulse-shaping in phase and amplitude

“…In the following we describe the design, simulation, fabrication, packaging, and characterization of the new MEMS chip, while another recent publication 18 is dedicated to the in depth presentation and discussion of the spectral and temporal shaping results obtained with it.…”
