    "abstract": "We report an optical dipole trap for calcium. The trap is created by focusing\na 488 nm argon-ion laser beam into a calcium magneto-optical trap. The\nargon-ion laser photo-ionizes atoms in the trap because of a near-resonance\nwith the 4s4f 1F3 level. By measuring the dipole trap decay rate as a function\nof argon-ion laser intensity, we determine the 1F3 photo-ionization cross\nsection at our wavelength to be approximately 230 Mb.",
