摘要
We describe a simple electro-optically activated external-cavity diode laser designed to provide high-speed, high-coherence tuning over gigahertz frequency ranges. Tuning as fast as 23 GHz/μs is demonstrated. Coherence measurements indicate transform-limited quiescent laser linewidth in observation windows as wide as ∼100 μs and transform-limited chirps. A self-heterodyne, cross-correlation-based coherence diagnostic is developed for characterizing phase coherence during high-speed chirps.
