Fast Compact Laser Shutter Using a Direct Current Motor and 3D Printing
Grace H. Zhang, Boris Braverman, Akio Kawasaki +1
We present a mechanical laser shutter design that utilizes a DC electric motor to rotate a blade which blocks and unblocks a light beam. The blade and the main body of the shutter…
Magic Wavelength for Hydrogen 1S-2S Transition
Akio Kawasaki
The magic wavelength for an optical lattice for hydrogen atoms that cancels the lowest order AC Stark shift of the 1S-2S transition is calculated to be 513 nm. The magnitude of AC…
Observation of Rapid Change of Crystalline Structure during the Phase Transition of the Palladium-Hydrogen System
Akio Kawasaki, Satoshi Itoh, Kunihiro Shima +4
We performed an X-ray diffraction experiment while palladium bulk absorbed and desorbed hydrogen to investigate the behavior of the crystalline lattice during the phase transition…
Two-Color Magneto-Optical Trap with Small Magnetic Field for Ytterbium
Akio Kawasaki, Boris Braverman, QinQin Yu +1
We report a two-color magneto-optical trap (MOT) for ytterbium atoms operating at a low magnetic field gradient down to 2 G/cm where a conventional MOT using the singlet transition…
