Abstract

We introduce a diode-based laser with a fast frequency noise of 30 Hz2/Hz, corresponding to a Lorentzian linewidth of 100 Hz. We examine its characteristics in detail. Our focus is on exploring the variations and similarities in frequency noise and linewidth reduction. Additionally, we present the locking capability of these systems when applied to medium finesse cavities. The results provide insights into the unique operational characteristics of these ultra-low noise lasers and their potential applications in quantum technology.
