Description

During the second visit, the semiconductor disk laser (SDL) systems developed at University of Strathclyde will be tested in the University of Birmingham’s Strontium optical clock setup. The systems transported are: a monobloc 461nm (P = 1W, Δν < 3 MHz, Volume = 9-l) , and a breadboard and a monobloc 689 nm (P > 150 mW, Δν < 500 Hz, Volume < 3-l). They have achieved the target performances and this joint experiment is the next step in the deliverables list of the UK National Quantum Technology Hub in Sensor and Metrology’s Work Package 3. From day one, laser performance, and its short and long term stability, including the measurement of red VECSEL system linewidth via beat-note measurement against a commercial laser system.
