Abstract

We found that laser pulses in the order of one nanosecond create significant through-thickness temperature gradients in an MO layer. Applying this effect to double-layered media, expansion of the laser power range for a writing process was demonstrated experimentally. These results imply that a combination of short and long pulses could provide a new approach to direct overwrite.
