On the angular dependence of focused laser ablation by nanosecond pulses in solgel and polymer materials
Focused laser ablation by single laser pulses at varying angles of incidence is studied in two materials of interest: a solgel ~Ormocer 4! and a polymer ~SU8!. For a range of angles ~up to 70° from normal!, and for low-energy ~,20 mJ!, 40 ns pulses at 266 nm wavelength, the ablation depth along the direction of the incident laser beam is found to be independent of the angle of incidence. This a...
متن کاملA Study of Angular Dependence in the Ablation Rate of Polymers by Nanosecond Pulses
Measurements of ablation rate have traditionally been carried out only at normal incidence. However, in real-world applications ablation is often carried out at oblique angles, and it is useful to have prior knowledge of the ablation rate in this case. Detailed information about the angular dependence is also important for the development of ablation simulation tools, and can provide additional...
متن کاملImproved model for the angular dependence of excimer laser ablation rates in polymer materials
Measurements of the angle-dependent ablation rates of polymers that have applications in microdevice fabrication are reported. A simple model based on Beer’s law, including plume absorption, is shown to give good agreement with the experimental findings for polycarbonate and SU8, ablated using the 193 and 248 nm excimer lasers, respectively. The modeling forms a useful tool for designing masks ...
متن کاملStudy of laser ablation using nano-second laser pulses
In this paper, the laser ablation process based on the irradiation of nanosecond pulsed lasers on a copper target surface in the presence of Helium gas is studied. The dynamical behaviors of the generated plasma in the helium gas and evaporated copper at the atmospheric pressure are examined using a laser pulse, laser wavelength of and intensity of 7×1010W/cm2. A one-dimensional thermal model ...
