With current endeavours in the UK and around the world to foster the development of new Quantum-based technologies (QT) to sense and detect previously unreachable interactions, such as underground structures and gas leakages, the generation of light sources with highly stabilised output wavelengths have become critical. Diode-pumped solid-state (DPSS) and external cavity diode (ECD) lasers are two of the ideal candidates for narrow linewidth single frequency generation. This paper will discuss some of their spectral performance differences.
