Instrumentation
Metrology Laboratory Instrumentation
The optics laboratory contains a suite of instruments for characterizing optical sources, particularly lasers, and the optical properties of materials. Some of these instruments are connected by single-mode optical fiber to JILA research groups laboratories. The fiber links allow the instruments to be used remotely. The results are read back from a server over a new high-speed local area network installed as part of the Keck lab. The measurements performed by some instruments do not allow intervening fiber; these instruments are located on carts so that they can moved into research labs. Others remain in the Keck Laboratory. The optics lab is also used for teaching alignment and operation of ultrafast lasers.
