An All-Fiber Laser System for Ultracold Atom Interferometer Experiments

Ultracold atom experiments rely on complex laser systems which typically use bulk optics in an optical bench setup. Here, we present an all-fiber laser system with sufficent switching speeds, laser power extinction, and polarization stability needed for rubidium cold-atom interferometer experiments. In addition to this, the laser system is portable, easy to align, and has a low sensitivity to temperature fluctuations and vibrational noise. We demonstrate this by performing a series of environmental tests on our laser system which is contained in a 1u rackmount server chassis. Our system represents a significant step forward in moving ultracold atom interferometer technology such as clocks, accelerometers, gravitometers, and gyroscopes out of the lab and into real-world implementations.
