Intensity stabilisation of optical pulse sequences for coherent control of laser-driven qubits
We demonstrate a system for intensity stabilisation of optical pulse sequences used in laser-driven quantum control of trapped ions. Intensity instability is minimised by active stabilisation of the power (over a dynamic range of > 10 4 ) and position of the focused beam at the ion. The fractiona...
