Energy efficiency of femtosecond laser ablation of polymer materials

Energy efficiency of femtosecond laser ablation of polymer materials

We present the results of an experimental study of the ablation spectral energy thresholds for a number of polymer materials ((C 2 F 4 ) n , (CH 2 O) n ) exposed to femtosecond (τ 0.5  ~ 45–70 fs) laser pulses (λ ~ 266, 400, 800 nm) under atmospheric conditions and under vacuum ( p  ~ 10–2 Pa). We h...

Zusammenfassung:We present the results of an experimental study of the ablation spectral energy thresholds for a number of polymer materials ((C 2 F 4 ) n , (CH 2 O) n ) exposed to femtosecond (τ 0.5  ~ 45–70 fs) laser pulses (λ ~ 266, 400, 800 nm) under atmospheric conditions and under vacuum ( p  ~ 10–2 Pa). We have analyzed the energy thresholds and the efficiency of optical, thermophysical, and gasdynamic processes in laser ablation vs. the laser pulse duration and photon energy.
