Femtosecond Laser Backside Ablation of Gold Film on Silicon Substrate

Lei, Shuting; Grojo, D.; Ma, J.; Yu, Xiaoming; Wu, H.

Femtosecond laser ablation of gold thin film on the front and backside of silicon substrate is investigated, with backside ablation being the focus and front side ablation for comparison. The experiments are performed using ...
From carrier dynamics inside fused silica to control of multiphoton-avalanche ionization for laser machining

Lei, Shuting; Grojo, D.; Barillot, T.; Gertsvolf, M.; Chang, Zenghu; Rayner, D. M.; Corkum, P. B. (Institute of Electrical and Electronics Engineers, 2010-07-20)

Using pump-probe measurements, we characterize carrier decay time inside fused silica and measure deeply bound self-trapped excitons. With pump-probe delay, we also control free carrier injection and the subsequent avalanche ...
