We report an optical dipole trap for calcium. The trap is created by focusing a 488-nm argon-ion laser beam into a calcium magneto-optical trap. The argon-ion laser photoionizes atoms in the trap because of a near-resonance with the 4s4f ¹F₃ level. By measuring the dipole-trap decay rate as a function of argon-ion laser intensity, we determine the ¹F₃ photoionization cross section at our wavelength to be approximately 230 Mb.
