A Simple, Versatile Laser System for the Creation of Ultracold Ground State Molecules

摘要: A narrow-linewidth, dual-wavelength laser system is vital for the creation of ultracold ground state molecules via stimulated Raman adiabatic passage (STIRAP) from a weakly bound Feshbach state. Here we describe how relatively simple apparatus consisting single fixed-length optical cavity can be used to narrow linewidth two different wavelength lasers required STIRAP simultaneously. The frequency each these referenced and continuously tunable away modes through use non-resonant electrooptic modulators. Self-heterodyne measurements suggest linewidths are reduced several hundred Hz. In context 87Rb133Cs produced magnetoassociation on resonance, demonstrate performance one- two-photon molecular spectroscopy. Finally, transfer rovibrational using STIRAP.
