Research Abstract |
We succeeded in producing a dual Bose-Einstein Condensate made of rubidium-87 atoms and potassium-41 atoms in an optical dipole trap. In order to have ample optical power for lattice potential, we developed a single frequency diode-pumped solid state (DPSS) laser at 1064nm. Furthermore, by using an optical trap whose wavelength at 809nm, we successfully canceled the gravitational sag difference caused by mass difference between rubidium and potassium atoms. By using interspecies Feshbach resonance, we realized miscible and immiscible mixture of Bose-Einstein Condensates.
