The investigation of spatio-temporal couplings (STCs) broadband light beams is becoming a key topic for the optimization as well applications ultrashort laser systems. This calls accurate measurements STCs. Yet, it only recently that such complete or spatio-spectral characterization has become possible, and so far mostly been implemented at output systems, where experiments take place. In this survey, we present first time STC different stages collection high-power all based on chirped-pulse...
We demonstrate for the first time, to best of our knowledge, ability extreme ultraviolet (XUV) Hartmann wavefront sensors characterize high charge vortex beams produced by high-order harmonic generation up order 25. also show that phase matched absorption limited is able maintain structure XUV beam even in a rather long (1 cm) medium.
Optical beams carrying orbital angular momentum are a very active field of research for their prospective applications, especially at short wavelengths. We consider here such produced through high-harmonic generation (HHG) in rare gas and analyze the characterization high-charge vortex structure by an extreme ultraviolet Hartmann wavefront sensor. show that HHG generally composed set numerous modes. The sensitivity intensity phase beam to infrared laser aberrations is investigated using...
We investigate the coherence of plasma-based soft X-ray laser (XRL) for different conditions that can alter electron density in gain region. first measure source temporal amplified spontaneous emission (ASE) mode. develop a data analysis procedure to extract both its spectral width and pulse duration. These findings are agreement with line shape simulations seeded operation experimental results. Utilizing deduced duration one-dimensional Bloch-Maxwell code, we reproduce properties...
We designed and manufactured an optical bench to characterize the EUCLID dichroic reflected wavefront at all useful incidences, polarization states each wavelength from 550nm 950nm. The multilayer coating adds indeed some phase effect that vary suddenly in function of wavelength. testbed architecture, main functionalities performances are presented. preliminary results obtained on mirror compared simulations based up-to-date model coating.
We present an experimental intensity and wavefront characterization of the infrared vortex driver as well extreme ultraviolet obtained through high harmonic generation in extended medium. In a loose focusing geometry, intense beam phase-matched absorption-limited 15 mm long Argon filled gas-cell permits single-shot structure. Moreover, our study validates multiplicative law momentum conservation even for such
We report temporal coherence measurement of solid-target plasma-based soft X-ray laser (XRL) in amplified spontaneous emission (ASE) mode. By changing the XRL pumping angle, we generate lasing at two-times higher electron density than routine condition. A relatively shorter time a angle indicates clear spectral signature gain region. probe amplification dynamics routine, and high conditions to confirm gain-duration reduction resulting from ionization gating latter case. also present recent...

We demonstrate that high harmonic generation when driven by vortex driver contaminated with various orbital angular momentum (OAM) modes, the upconverted EUV deviates from perturbative conversion law to exhibit a spectrum of OAM orders.
