We report long-term laser frequency stabilization using only the target laser and a pair of 5 m fiber interferometers, one as a frequency reference and the second as a sensitive thermometer to stabilize the frequency reference. When used to stabilize a distributed feedback laser at 795 nm, the frequency Allan deviation at 1000 s drops from 5.6 × 10-8 to 6.9 × 10-10. The performance equals that of an offset lock employing a second, atom-stabilized laser in the temperature control.

Abstract
We report long-term laser frequency stabilization using only the target laser and a pair of 5 m fiber interferometers, one as a frequency reference and the second as a sensitive thermometer to stabilize the frequency reference. When used to stabilize a distributed feedback laser at 795 nm, the frequency Allan deviation at 1000 s drops from 5.6 × 10-8 to 6.9 × 10-10. The performance equals that of an offset lock employing a second, atom-stabilized laser in the temperature control.File in questo prodotto:
