DESCRIPTION - summary of the module content
Nonlinear optics allows us to change the colour of light, manipulate its shape in space and time, and to create the shortest events ever made by humans. This module explores how light interacts with matter to create images, and the exciting nonlinear interactions that take place when light is squeezed into very short pulses.
You’ll get to see inside laser research laboratories for demonstrations of nonlinear optical imaging.
You’ll also learn the Physics that explains why gin & tonic fluoresces under UV light, and how to make cocktails that glow in the dark.
Pre-requisite modules: PHY1023, PHY1026, PHY2021 or equivalent modules.

AIMS - intentions of the module
Nonlinear optical imaging has emerged as a powerful tool offering significant advantages over conventional optical methods. This module aims to give students an introduction into the fundamental Physics underpinning these techniques, an overview of the instrumentation used, and their application in modern research applications.

RE-ASSESSMENT NOTES
An original assessment that is based on both examination and coursework, tests, etc., is considered as a single element for the purpose of referral; i.e., the referred mark is based on the referred examination only, discounting all previous marks. In the event that the mark for a referred assessment is lower than that of the original assessment, the original higher mark will be retained.
Physics Modules with PHY Codes
Referred examinations will only be available in PHY3064, PHYM004 and those other modules for which the original assessment includes an examination component - this information is given in individual module descriptors.
