DESCRIPTION - summary of the module content

Nonlinear optics provides access to light-matter interactions that are not accessible with conventional (linear) optical imaging techniques and can give novel information regarding the microscopic structure and chemical composition of a wide range of materials. This module will introduce the fundamental principles of non-linear optics (NLO) and explain how it can be applied to reveal novel information regarding material structure and function. Examples from recent research publications will be used to highlight how NLO is making a significant contribution towards advancing our understanding in key materials and life-science research challenges.

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.

Original Form of Assessment Form of Re-assessment ILOs Re-assessed Time Scale for Re-assessment
Whole module Written examination (100%) 1-11 August/September assessment period

Re-assessment is not available except when required by referral or deferral.

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.
