New 157 nm Laser Ablation System

The following video (573 MB, h264) shows clean and controlled ablation of natural quartz at 157 nm using the new laser ablation instrumentation that we designd and built for the FIERCE lab at Goethe University Frankfurt am Main.

Spot Size: 60 µm
Rep. Rate: 10 Hz
Scan Speed: 20 µm/s
Fluence: 3 J/cm²
Sample: Natural Quartz (Tobias Erhardt)
