TLDR
A compact 20 Hz repetition-rate mid-IR OPCPA system operating at a central wavelength of 3900 nm with the tail-to-tail spectrum extending over 600 nm and delivering 8 mJ pulses that are compressed to 83 fs opens a range of unprecedented opportunities for tabletop ultrafast science.Abstract:
We demonstrate a compact 20 Hz repetition-rate mid-IR OPCPA system operating at a central wavelength of 3900 nm with the tail-to-tail spectrum extending over 600 nm and delivering 8 mJ pulses that are compressed to 83 fs (<7 optical cycles). Because of the long optical period (∼13 fs) and a high peak power, the system opens a range of unprecedented opportunities for tabletop ultrafast science and is particularly attractive as a driver for a highly efficient generation of ultrafast coherent x-ray continua for biomolecular and element specific imaging.read more

A novel few-cycle optical source in the mid-infrared
TL;DR: This thesis designed, simulated, and implemented a novel optical pulse generation system which is shown to be able to generate exceptionally short optical pulses in the mid-infrared, tunable from 2-4psm with pulse widths as low as 1.5pum.

Coherent forward scattering of γ-ray and XUV radiation in the medium with the modulated quasi-resonant transition
TL;DR: In this article, the authors established a close physical analogy between coherent forward scattering of γ-ray radiation in the vibrating quasi-resonant nuclear absorber and the XUV field propagation in the quasi-reonant atomic medium in the presence of the moderately strong IR field.

Generation of sub-half-cycle 10 µm pulses through filamentation at kilohertz repetition rates
TL;DR: The generation of sub-half-cycle phase-stable pulses with the carrier wavelength of 10.2 µm through two-color filamentation in nitrogen and it is found that the 10 kHz repetition rate of the light source causes the fluctuation of the pulse energy on a few hundred millisecond time scale.
High Energy, High Average Power, Picosecond Laser Systems To Drive Few-cycle Opcpa
TL;DR: The HERACLES project as discussed by the authors developed in the Laser Plasma Laboratory at CREOL (University of Central Florida, USA) developed a few-cycle OPCPA facility to achieve peak power of more than 100 GW with mJ-level pulse energy, W-level average power and more than 10 W average power.

The attosecond nonlinear optics of bright coherent X-ray generation
TL;DR: In this paper, the Roentgen X-ray tube was used for high-order harmonic generation with small-scale femtosecond laser technology, which combines the microscopic attosecond science of atoms driven by intense laser fields with the macroscopic extreme nonlinear optics of phase matching.

Infrared Two-Color Multicycle Laser Field Synthesis for Generating an Intense Attosecond Pulse
TL;DR: The proposed method enables the requirements for the pump pulse duration to be relaxed but also to reduce ionization of the harmonic medium, which opens the door to create an intense isolated attosecond pulse using a conventional femtosecond laser system.
