Atomic Dipole Traps with Amplified Spontaneous Emission: A Proposal

Understand

We propose what we believe to be a novel type of optical source for ultra-cold atomic Far Off-Resonance optical-dipole Traps (FORTs).

• The source is based on an Erbium Amplified Spontaneous Emission (ASE) source that seeds a high power Erbium Doped Fiber Amplifier (EDFA).
• The main interest of this source is its very low coherence length, thus allowing an incoherent superposition of several trapping beams without any optical interference.
• The behavior of the superimposed beams is then a scalar sum greatly simplifying complex configurations.
