Hug D, Dax A, Trisorio A, Carreto R, Sudmeyer T, Resan B
Opt Express . 2024 Nov; 32(22):39887-39895. PMID: 39573796
Ultra short pulse Ti:sapphire lasers, crucial for most demanding applications, have traditionally been complex and costly due to their pump sources. GaN-based laser diodes offer new prospects for pumping, yet...

Prat E, Haddad A, Arrell C, Augustin S, Boll M, Bostedt C, et al.
Nat Commun . 2023 Aug; 14(1):5069. PMID: 37604879
X-ray free-electron lasers (FELs) are state-of-the-art scientific tools capable to study matter on the scale of atomic processes. Since the initial operation of X-ray FELs more than a decade ago,...

Dax A, Sydlo C, Divall E, Hauri C, Huppert M, Schaedler M, et al.
Opt Express . 2022 Apr; 30(9):15495-15511. PMID: 35473268
The arrival time jitter and drift of the photocathode drive laser has an important impact on the performance of a Free-Electron-Laser (FEL). It adversely affects the beam energy jitter, bunch...

Soter A, Aghai-Khozani H, Barna D, Dax A, Venturelli L, Hori M
Nature . 2022 Mar; 603(7901):411-415. PMID: 35296843
When atoms are placed into liquids, their optical spectral lines corresponding to the electronic transitions are greatly broadened compared to those of single, isolated atoms. This linewidth increase can often...

Hori M, Aghai-Khozani H, Soter A, Dax A, Barna D
Nature . 2020 May; 581(7806):37-41. PMID: 32376962
Charged pions are the lightest and longest-lived mesons. Mesonic atoms are formed when an orbital electron in an atom is replaced by a negatively charged meson. Laser spectroscopy of these...

Abela R, Alarcon A, Alex J, Arrell C, Arsov V, Bettoni S, et al.
J Synchrotron Radiat . 2019 Jul; 26(Pt 4):1073-1084. PMID: 31274430
The SwissFEL soft X-ray free-electron laser (FEL) beamline Athos will be ready for user operation in 2021. Its design includes a novel layout of alternating magnetic chicanes and short undulator...

Gorgisyan I, Ischebeck R, Erny C, Dax A, Patthey L, Pradervand C, et al.
Opt Express . 2018 Mar; 25(3):2080-2091. PMID: 29519055
The two-color operation of free electron laser (FEL) facilities allows the delivery of two FEL pulses with different energies, which opens new possibilities for user experiments. Measuring the arrival time...

Ullmann J, Andelkovic Z, Brandau C, Dax A, Geithner W, Geppert C, et al.
Nat Commun . 2017 May; 8:15484. PMID: 28508892
Electrons bound in highly charged heavy ions such as hydrogen-like bismuth Bi experience electromagnetic fields that are a million times stronger than in light atoms. Measuring the wavelength of light...

Hori M, Aghai-Khozani H, Soter A, Barna D, Dax A, Hayano R, et al.
Science . 2016 Nov; 354(6312):610-614. PMID: 27811273
Charge, parity, and time reversal (CPT) symmetry implies that a particle and its antiparticle have the same mass. The antiproton-to-electron mass ratio [Formula: see text] can be precisely determined from...

Pohl R, Nez F, Fernandes L, Amaro F, Biraben F, Cardoso J, et al.
Science . 2016 Aug; 353(6300):669-73. PMID: 27516595
The deuteron is the simplest compound nucleus, composed of one proton and one neutron. Deuteron properties such as the root-mean-square charge radius rd and the polarizability serve as important benchmarks...
