Miniature, Compact Laser System for Ultracold Atom Sensors

摘要

As ultracold atom sensors begin to see their way to the field, there is a growing need for small, accurate, and robust laser systems to cool and manipulate atoms for sensing applications such as magnetometers, gravimeters, atomic clocks and inertial sensing. In this paper we present a frequency-agile, butterfly packaged laser source, absolutely referenced to an atomic transition. We also present the entire laser system, including a fiber-coupled optical amplifier and liquid crystal shutters, replacing a laboratory table's worth of optics with a system the size of a paperback novel.
