“…Presently, the latter are dominated by liquid crystal arrays which have proven very reliable [7]. Their main limitation is the material transmission cut-off in the visible-UV region, an issue only recently addressed by the group of Yamashita [8]. Acousto-optic modulators are an interesting alternative, as they are characterized by very easy alignment and operation.…”

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.

“…2). After splitting this broadband light source into two different wavelength channels via a broadband dichroic mirror (DM), we plan to compress the different spectral regions using custom-designed double-chirped mirrors (DCM Vis-NIR ) and a UV spatial-light modulator (SLM) [6]. Finally, we will recombine the two channels by another broadband dichroic mirror.…”

Abstract:We demonstrate phase-stable, ~0.4-mJ optical waveforms based on induced-phase modulation for generating sub-fs optical pulses. Using custom-designed double-chirped mirrors and a spatial light modulator, such optical waveforms will become a versatile tool for strong-field attoscience.Ultrashort optical pulses with high energy and multi-octave bandwidth have been greatly desired for the generation of intense monocycle optical pulses. This is because those pulses are expected to be crucially important as driver pulses for efficient generation of isolated attosecond pulses with sub-100-as duration in the extreme-ultraviolet (XUV) region. However, the generation of such pulses with both high energy and multioctave bandwidth has been a very challenging subject so far. To overcome the problem, one of the most popular techniques is coherent optical waveform synthesis, which means the generation of custom-tailored, intense, fewcycle or even sub-cycle optical waveforms by coherently stitching together separate spectral portions. Currently, coherent waveform synthesis is one of the most intriguing and promising frontiers of attosecond science and strong-field physics, opening up unprecedented prospects, e.g., for precision control of strong-field interactions in atoms, molecules and solids, generation of intense isolated attosecond pulses, and attosecond pump-probe spectroscopy employing ultrashort pulses in the VIS/IR and XUV/soft-X-ray regions.Up to now, coherent waveform synthesis based on self-phase modulation (SPM) in a neon-filled hollow-core fiber (HCF) compressor allowed for the generation of sub-cycle ~300-µJ optical pulses [1]. For pursuing the synthesis of the shortest possible pulses within this scheme, the total output energy of this multi-channel synthesizer is limited to a few tens of µJs mainly by the UV channel containing the smallest pulse energy [2], thus preventing further energy upscaling to the (multi-)mJ level, which is required for many interesting applications in attosecond science. A potential solution out of this dilemma is the application of induced-phase modulation (IPM) [3] based on the interaction between two (or more) co-propagating optical pulses of different colors and relatively long pulse durations in a gas-filled HCF. The IPM technique offers control over the spectral shape by adjusting the relative intensity ratio and the relative delay between the input pulses and allows a more efficient generation of broader-band optical pulses than those produced solely by SPM. Such an IPM-based synthesizer is expected to greatly relieve the energy-scaling bottleneck in the UV region [4], and the enhanced spectral broadening of the UV region is particularly appealing for the realization of ultrahigh HHG conversion efficiencies in bright coherent tabletop high-harmonic sources.In our earlier work, we already generated transform-limited (TL) 2.6-fs, 3.6-µJ optical pulses centered at 600 nm by compensating for the chirp of the ultrabroad spectrum generated by IPM in an argon-filled HCF [3].
