Investigation of realization limits of ultrashort pulse written volume-Bragg-gratings by means of higher repetition rates

We report on the investigation of realization limits of ultrashort pulse written volume-Bragg-gratings with respect to the laser pulse repetition rate. The VBGs are directly inscribed in fused silica by applying ultrashort laser pulses and the phase mask scanning technique. In order to investigate the scaling potential of the realization process of such gratings by means of higher repetition rates we investigate the fundamentally given material constraints. These investigations will help to pave the way of this realization scheme for VBGs beyond the prototype regime.
