Mid-Wave Infrared Gas-Filled Hollow Core Fiber Lasers for Counter IR Sensors
Abstract
This project was formed in order to investigate the properties of hollow-core optical fibres for laser generation in gases and counter-IR sensors. The envisaged wavelengths in the infrared target the atmospheric windows 3-4 micrometer and 4.5-5 micrometer. Optical fibres guiding these wavelengths would also need to contain the lasing gas and guide light at the pump wavelengths. The project timing was particularly affected by UK and worldwide restrictions from the COVID-19 pandemic. We were not able to overlap the start of the project with the end of previous projects working on hollow optical fibres of this type. As well as a turnover of researchers, PhD and post-doctoral, there was a challenging recruitment environment for a researcher for this project. As a result much of the project time has been spent on training and investigating fabrication processes. This has resulted in a greatly improved understanding of the process to enable repeatable and uniform fabrication, which opens up new capabilities in mid-infrared hollow optical fibres for lasers, light sources and sensors.
