An iodine-stabilized laser is a highly precise optical frequency standard where laser light is stabilized by locking it to the molecular absorption lines of iodine. This provides exceptional frequency stability and accuracy, making it a valuable tool in applications such as metrology, telecommunications, and fundamental physics research.
