Two-Photon Ionization of the Calcium 4S3D 1D2 Level in an Optical Dipole Trap Two-Photon Ionization of the Calcium 4S3D 1D2 Level in an Optical Dipole Trap
The 488 nm light also photo-ionizes the trapped atoms due to a near-resonant transition to the 4s4f 1F3 level. These ions leave the trap and are detected to determine the trap decay rate. By measuring this decay rate as a function of 488 nm intensity, we determine the 1F3 photo-ionization cross section at this wavelength to be approximately 230 Mb.
