Modelling and Fabrication of Gallium Nitride Lasers for Atomic Clocks
This paper presents the design and modelling of a 3<sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">rd</sup> order gallium nitride (GaN) distributed feedback (DFB) laser for the cooling transition in Sr<sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">+</sup> optical atomic clocks. A compact design of the laser source operating at 422 nm, with sufficiently narrow linewidth and high power output, is favoured to hit the required specifications for this application. These lasers provide a viable solution to bulky, benchtop lasers which are often frequency doubled to hit the required wavelengths, leading towards more compact systems.
