Abstract

Fourier-limited and tunable nanosecond pulses are essential for applications that rely on high-intensity interactions between light and atoms. These applications require precise and wide tunability across a large range of wavelengths (expanding from the UV to the near-IR). The vast interest in producing and integrating pulsed tunable narrow linewidth light is further fuelled by applications in quantum technology. The main challenge here is in the production of many (hundreds to thousands) individually tunable, narrow-band pulses simultaneously. Photonic integrated circuits (PICs) are expected to provide the scalability and simplicity required for these quantum technology-based sensing systems and applications, but there are still many obstacles to overcome. Among these are improvements in active materials, such as direct gain and laser output in the green-yellow spectral range.
