Low-loss flake-graphene saturable absorber mirror for laser mode-locking at sub-200-fs pulse duration
B. V. Cunning, C. L. Brown, D. Kielpinski
Saturable absorbers are a key component for mode-locking femtosecond lasers. Polymer films containing graphene flakes have recently been used in transmission as laser mode-lockers,…
Laser cooling of new atomic and molecular species with ultrafast pulses
D. Kielpinski
We propose a new laser cooling method for atomic species whose level structure makes traditional laser cooling difficult. For instance, laser cooling of hydrogen requires single-fr…
Laser cooling of trapped ytterbium ions with an ultraviolet diode laser
D. Kielpinski, M. Cetina, J. A. Cox +1
We demonstrate an ultraviolet diode laser system for cooling of trapped ytterbium ions. The laser power and linewidth are comparable to previous systems based on resonant frequency…
Topological vortex formation in a Bose-Einstein condensate
A. E. Leanhardt, A. Görlitz, A. P. Chikkatur +4
Vortices were imprinted in a Bose-Einstein condensate using topological phases. Sodium condensates held in a Ioffe-Pritchard magnetic trap were transformed from a non-rotating stat…
Propagation of Bose-Einstein condensates in a magnetic waveguide
A. E. Leanhardt, A. P. Chikkatur, D. Kielpinski +4
Gaseous Bose-Einstein condensates of 2-3 million atoms were loaded into a microfabricated magnetic trap using optical tweezers. Subsequently, the condensates were released into a m…
