Influence of MHz bursts on the ablation efficiency of fused silica

We report on micromilling of fused silica using a 1030 nm femtosecond laser with an intraburst repetition frequency of 40 MHz. Milling of cavities reveals a monotonously increasing ablation efficiency with increasing subpulse number, while the ablation threshold of each subpulse decreases. These res...
