Abstract
We present the development of a laser damage and ablation test-bench able to accommodate ultrashort pulses down to 10 fs pulse duration. The laser test-bench is operated in air and we demonstrate its capability to accurately measure the damage and ablation characteristics of optical materials, like fused silica, irradiated by single ultrashort pulses of < 15 fs pulse duration. The careful characterization of beam propagation allows us to ascertain the precise retrieval of laserinduced damage and ablation threshold fluences as well as to identify the energetic regime yielding to beam filamentation.
