The PST beamline: a laboratory-scale setup for extreme ultraviolet ptychography in the silicon transparency window

Extreme ultraviolet microscopy and wavefront sensing are key challenges in the development of next-generation ultrafast applications. Ptychography offers a single solution to both of the aforementioned challenges. Originally proposed and developed in the electron and synchrotron communities, the increase in flux and stability of high harmonic sources has enabled the transfer of ptychography to the laboratory. Here, we present the status of the PST beamline, a versatile tool for laboratory-scale XUV ptychography in the silicon transparency window, including the latest experimental results demonstrating sub-30nm lateral resolution at 13.5 nm wavelength.

Microwatt-class intra-oscillator high harmonic generation in argon, krypton, and xenon

Time and Frequency Laboratory (LTF), Switzerland

We present an intra-oscillator high harmonic generation source based on a 100-fs Kerr lens mode-locked Yb:YAG thin-disk laser. We generate XUV light with an average power of 10 µW at 30 eV in argon, 12 µW at 25 eV in krypton, and 30 µW at 20 eV in xenon.

Continuously tunable high photon flux high harmonic source at 50 – 70 eV

Alexander Kirsche1,2, Robert Klas1,2, Martin Gebhardt1,2, Lucas Eisenbach1, Wilhelm Eschen1, Joachim Buldt1, Henning Stark1, Jan Rothhardt1,2,3, Jens Limpert1,2,3

In this contribution a fully tunable high harmonic source is presented, which delivers a photon flux of over 1x10^11 photons/s per harmonic line in the range of 50 eV to 70 eV. This table-top waveguide-based XUV source is driven by a 50 W, 1.0 mJ, 36 fs nonlinearly post-compressed fiber laser centered at 1030 nm with a repetition rate of 50 kHz. The tunability of the XUV spectrum is achieved by exploiting the intensity-dependent blueshift of the driving laser field in a noble gas within the waveguide.

Laser wakefield accelerators as a broadband radiation source

Amina Hussein

University of Alberta, Canada

A Laser Wakefield Accelerator (LWFA) can accelerate electrons up to many GeV energies using the accelerating field structure in the wake of a high-power laser pulse propagating through low-density plasma. Within the accelerating structure, energetic electrons can undergo betatron oscillations, emitting a bright, broadband source of keV X-rays with femtosecond-scale duration. A LWFA can also drive wavelength-tunable pulses of infrared radiation with high focusability through spectral broadening of the laser pulse within plasma waves. In this talk, I will discuss the generation and application of these diverse radiation sources.
