We describe the visualization of 3D optical lattices based on Sisyphus cooling implemented with open source software.As a main framework to build the simulation software, we utilized Python and its open source libraries, such as Numpy, Scipy, TkInter, and QuTiP.Along with the computational and simulational part, the software comes up with a graphical user interface (GUI).Thus, we expect researchers without programming background can easily access the software and utilize it for guiding their experimental implementations of optical lattices.The software has been published to a Github repository ( https://github.com/ohpyupi/3dopticallattice).Utilizing the software, we plot the adiabatic light shift potentials found by diagonalizing the effective Hamiltonian for the light shift operator.Our program incorporates a variety of atomic ground state configurations with total angular momentum ranging from J=½ to J = 4 and a variety of laser beam configurations including the twobeam lin⊥lin configuration, the fourbeam umbrella configuration, and four beams propagating in two orthogonal planes.In addition to visualizing the lattice, the program also evaluates lattice parameters such as the vibrational frequency for atoms trapped deep in the wells.
