- Abstract
- In the field of attosecond science, photoelectron spectroscopy and interferometry stand as a central topic not only for its ability to characterise attosecond pulses but also for its ability to make time resolved measurements of electron dynamics. This feature allows for its application across the many fields which depend on the behaviour of electrons. For these reasons, there is significant interest in improving these techniques. One such candidate is the implementation of quantum light states to replace the typical coherent light used for interferometry. In the past, this was not possible due to the weakness of quantum light sources. However, recent development has shown that high intensity bright squeezed vacuum sources are possible and... (More)

However, recent development has shown that high intensity bright squeezed vacuum sources are possible and can be made to have high enough intensities in order to drive nonlinear processes, which allows for possibilities within attosecond science. For this work, we will begin developing and characterising an intense bright squeezed vacuum source to be used for applications in photoelectron metrology. (Less)
- Popular Abstract
- In what is considered a blip in time within the universe, humanity has learned to interact with the natural world in unimaginable ways. In a matter of only a few hundred years, we have gone from making our first observations of electromagnetism to theorizing and mastering it in all manner of domains. Whether it is the application of electronics, optics or radio transmission, the very device you are reading this on has wide sweeping dependence on humanity's mastery of the electromagnetic field.
A standout modern tool that has come of this understanding is the laser; it is both a very simple and very complicated thing. To most it is merely a black box which emits a beam of light, but to some it is an extremely powerful measurement device....

In a matter of only a few hundred years, we have gone from making our first observations of electromagnetism to theorizing and mastering it in all manner of domains. Whether it is the application of electronics, optics or radio transmission, the very device you are reading this on has wide sweeping dependence on humanity's mastery of the electromagnetic field.
A standout modern tool that has come of this understanding is the laser; it is both a very simple and very complicated thing. To most it is merely a black box which emits a beam of light, but to some it is an extremely powerful measurement device. With this device, we have managed to investigate every corner of our world. From the night sky to a single electron and everything between, we have used the laser to teach us about our universe. The possibilities of this device are seemingly endless. However, as we get further into our investigation, the access and need for more exotic tools increases. One such instance of this is quantum light. Features of this phenomenon exist everywhere in the universe, but are so quiet that they are only ever felt in the coldest and darkest corners. Since the discovery of this in the mid 20th century, we have been working towards capturing this physics. The impact of this work has been felt in many unexpected places such as in the development of quantum computers and the detection of gravitational waves.
For this project, we aim to continue this story by amplifying this tiny effect to enormous scale. By shaping these quantum whispers into a screaming pulse of light, we may observe how it interacts with the world in a no longer so subtle manner. In this way, we look to bridge the topics of quantum optics and attosecond science into an exciting new forefront of humanities story with electromagnetism. (Less)
