Broadband Continuous Spectral Control of a Single Wavelength Polymer-Based Solid-State Random Laser

Bhupesh Kumar, Sebastian Schulz, Patrick Sebbah

We demonstrate temperature-controlled spectral tunability of a partially-pumped single-wavelength random laser in a solid-state random laser based on DCM (4-dicyanomethylene-2-meth…

Ultrafast MHz-rate burst-mode pump-probe laser for the FLASH FEL facility based on nonlinear compression of ps-level pulses from an Yb-amplifier chain

Marcus Seidel, Federico Pressacco, Oender Akcaalan +24

The Free-Electron Laser (FEL) FLASH offers the worldwide still unique capability to study ultrafast processes with high-flux, high-repetition rate XUV and soft X-ray pulses. The va…

A self-referenced in-situ arrival time monitor for X-ray free-electron lasers

Michael Diez, Andreas Galler, Sebastian Schulz +11

We present a novel, highly versatile, and self-referenced arrival time monitor for measuring the femtosecond time delay between a hard X-ray pulse from a free-electron laser and an…

Femtosecond X-ray emission study of the spin cross-over dynamics in haem proteins

Dominik Kinschel, Camila Bacellar, Oliviero Cannelli +26

In haemoglobin (consisting of four globular myoglobin-like subunits), the change from the low-spin (LS) hexacoordinated haem to the high spin (HS) pentacoordinated domed form upon…

A Hilbert Transform method for measuring linear and nonlinear phase shifts imparted by metasurfaces

Laura C. Wynne, Hamish T. Ballantyne, Xin Li +2

Nonlinear metasurfaces that dynamically manipulate the phase of a passing light beam are of interest for a wide range of applications. The controlled operation of such devices requ…
