Small-sized Dichroic Atomic Vapor Laser Lock (DAVLL)

摘要

Two, lightweight diode laser frequency stabilization systems designed forexperiments in the field are described. A significant reduction in size andweight in both models supports the further miniaturization of measurementdevices in the field. Similar to a previous design, magnetic-field lines arecontained within a magnetic shield enclosing permanent magnets and a Rb cell,so that these DAVLL systems may be used for magnetically sensitive instruments.The Mini-DAVLL system (49 mm long) uses a vapor cell (20 mm long), and does notrequire cell heaters. An even smaller Micro-DAVLL system (9mm long) uses amicro-fabricated cell (3 mm square), and requires heaters. These new systemsshow no degradation in performance with regard to previous designs, whileconsiderably reducing dimensions.
