PHYC40930 Ultrafast Soft X-ray Photonics

Academic Year 2021/2022

The module is organized in two parts:

The first part delivers a brief recap of laser theory, including the generation of ultra-fast laser pulses in the femto and attosecond regime. It will then introduce non-linear optics, second and higher harmonic generation, non-linear mixing and experimental techniques such as pump and probe, optical parametric oscillators and up- and down conversion. This is followed by methods to measure ultra-fast pulses: autocorrelation, frequency resolved optical gating and related imaging techniques.

The second part of the module provides an overview and develops understanding of the state-of-the-art in soft x-ray light sources. In the spectral region from 1 - 100 nm electromagnetic radiation interacts very strongly with matter. The module explores the main principles, and experimental realisation, of methods to generate intense sources at these wavelengths and their key applications as a tool for fabricating, probing and characterising matter - including SXR light for nanoprocessing and imaging nanostructures, and the imaging of biological samples in the “water window”.

Learning Outcomes:

The module will provide an in-depth understanding of ultra-fast laser pulse generation and will provide a solid foundation of light-matter interactions at such time scales. The students will be able to explain non-linear optics and the required experimental techniques to measure ultra-fast events in physics, including higher harmonics, pump and probe, autocorrelation and frequency resolved optical gating.
You will be able to explain the interaction of soft x-ray radiation with matter, both qualitatively and quantitatively. You will develop an understanding of the properties, and calculate key parameters, of various SXR sources, such as plasma-based sources, soft x-ray lasers, free electron lasers and attosecond pulse generated from high harmonics. This will allow you to analyse the principles, design and operation of modern SXR optical systems, and critically discuss fabrication, metrology and imaging in the soft x-ray region.
