Long-range filamentary propagation of subpicosecond ultraviolet laser pulses in fused silica

We report on what is to our knowledge the first observation of subpicosecond ultraviolet laser pulse filamentation in transparent solid materials. Robust filaments were created in fused silica and observed over distances that exceed 3 cm in length. Intensities as high as 10(13) W/cm2 were found to b...

Description
Summary:We report on what is to our knowledge the first observation of subpicosecond ultraviolet laser pulse filamentation in transparent solid materials. Robust filaments were created in fused silica and observed over distances that exceed 3 cm in length. Intensities as high as 10(13) W/cm2 were found to be transported in the filamented beam without material damage in the bulk of the fused-silica sample.
