In this project we will develop a compact, narrow-linewidth laser system to achieve the performance required for quantum technology applications. This project will aim to address the requirements for use in Rb based quantum sensors with a practical narrow linewidth laser system at 780 nanometers.</ns2:abstractText></ns2:project>
