A frequency locked laser diode for interferometric sensing systems

David J. Webb, Julian D.C. Jones, David A. Jackson

Research output: Contribution to journalArticlepeer-review


Interferometric sensors for slowly varying measurands, such as temperature or pressure, require a long term frequency stability of the source. We describe a system for frequency locking a laser diode to an atomic transition in a hollow cathode lamp using the optogalvanic effect.
