Quasi-Phase-Matched Materials for Active Sensing in the Midinfrared Waveband

Lead Research Organisation: University of Southampton
Department Name: Optoelectronics Research Ctr (closed)

Abstract

Commercially available nonlinear optical crystals are used in a number of defence and civilian applications to access mid-infrared wavelengths that would otherwise not be available from standard laser systems. In this project the student will learn to fabricate novel nonlinear materials needed to access the far-infrared spectrum where chemical fingerprinting can be performed. The student will also learn to design and build laser systems for upconversion detection, a technique used to convert invisible radiation to visible, detectable wavelengths and enable imaging in difficult conditions.

Description Gained significant insight into manipulating certain materials which will eventually be used for wavelength conversion with partners at DSTL.
Also gained significant knowledge on the physical machining of certain materials to restructure them (again for wavelength conversion). This knowledge transfers from the award holder to their peers to allow significant advances in the field of precision machining (which is not typically associated with optics).
Exploitation Route Outcome of this research could be used for mid-infrared wavelength conversion and associated applications (chemical detection, mid-IR lasing, spectrometry, etc...), particularly in the UK defence industry. Further outcomes include the precision machining of certain materials for optics purposes, which is a knowledge shared and used among peers for their separate projects.
