Alan Deviation Chart

Allan Deviation of a 200 mm ULE cavity, derived from a three-cornered hat measurement. This laser system used a 1550 nm laser, locked using SLS’s versatile FPGA locking electronics. The red diamonds show fractional instability using no drift removal. The drift may be removed via feed-forward using the FPGA locking system, for drift-free performance, shown in blue.
