The 488 nm line from an Ar-ion laser is used for gating and gratings are written using a Ti:sapphire laser operating in the range from 788 to 840 nm. The dependence of holographic recording on grating and writing intensity is investigated. A saturation of the sensitivity is found for 2 W/cm2 of grating intensity. A threshold photon energy of 1.53 eV for the second excitation step is observed. © 1999 American Institute of Physics. |
