Abstract
The magnitude, erasure fluence, and dark erasure time constants for photorefractive index gratings written with single 30 ps pulses of between 1 and 15 mJ cm-2 at 0.532 μm have been reported previously1,2. Here we report, for comparison, cw measurements at 0.515 μm of these characteristics in the same crystal sample.
