Designing and Building Laser Locking Mechanisms
Dr. Bergeson’s ultracold plasma experiment requires laser frequencies precisely tuned to atomic transitions. This tuning is currently achieved with 18 locking circuits. Some have been built by students while some are commercial devices costing more than $2500. We have designed a circuit which improves upon the previous circuits, with the end result being devices comparable to the commercial products for a fraction of the price.
