0.5 keV soft X-ray attosecond continua
S. M. Teichmann, F. Silva, S. L. Cousin +2
Attosecond light pulses in the extreme ultraviolet have drawn a great deal of attention due to their ability to interrogate electronic dynamics in real time. Nevertheless, to follo…
Making of a nonlinear optical cavity
R. MartÃnez-Lorente, G. J. de Valcárcel, A. Esteban-MartÃn +3
In the article we explain in detail how to build a photorefractive oscillator (PRO), which is a laser-pumped nonlinear optical cavity containing a photorefractive crystal. The spec…
Continuous spectra in high-harmonic generation driven by multicycle laser pulses
W. Holgado, C. Hernández-GarcÃa, B. Alonso +5
We present observations of the emission of XUV continua in the 20-37 eV region by high harmonic generation (HHG) with - pulses focused onto a Kr gas jet. The und…
Measurement of the emittance of accelerated electron bunches at the AWAKE experiment
D. A. Cooke, F. Pannell, G. Zevi Della Porta +81
The vertical plane transverse emittance of accelerated electron bunches at the AWAKE experiment at CERN has been determined, using three different methods of data analysis. This is…
Inline self-diffraction dispersion-scan of over octave-spanning pulses in the single-cycle regime
M. Canhota, F. Silva, R. Weigand +1
We present an implementation of dispersion-scan based on self-diffraction (SD d-scan) and apply it to the measurement of over octave-spanning sub-4-fs pulses. The results are compa…
Engineered arrays of NV color centers in diamond based on implantation of CN- molecules through nanoapertures
P. Spinicelli, A. Dréau, L. Rondin +9
We report a versatile method to engineer arrays of nitrogen-vacancy (NV) color centers in dia- mond at the nanoscale. The defects were produced in parallel by ion implantation thro…
Experimental demonstration of phase bistability in a broad area optical oscillator with injected signal
R. MartÃnez-Lorente, A. Esteban-MartÃn, E. Rolán +3
We demonstrate experimentally that a broad area laser-like optical oscillator (a nondegenerate photorefractive oscillator) with structured injected signal displays two-phase patter…
Multi-octave supercontinuum from mid-IR filamentation in bulk
F. Silva, D. Austin, A. Thai +4
In supercontinuum generation, various propa- gation effects combine to produce a dramatic spec- tral broadening of intense ultrashort optical pulses with far reaching possibilities…
