Effect of Auxiliary Heating on the Properties of Nanosecond Laser Ablation of Aluminum Alloys
摘要: 为了提高纳秒脉冲激光加工效率，本文采用热辅助加热手段，对铝合金靶材进行预处理，通过数值仿真得到，辅热会提高金属靶材的吸收率，从而使靶材对后续纳秒脉冲激光的利用率提高，且随着辅热温度的增加，靶材温升效果明显增强，并在辅热温度达到靶材熔点时，其温升效果产生阶跃。
Abstract: In order to improve the efficiency of nanosecond pulse laser processing, this paper adopts heat- assisted heating means to pretreat the aluminum alloy target, and it is obtained through numerical simulation that the auxiliary heat will improve the absorption rate of the metal target, so that the utilization rate of the target for the subsequent nanosecond pulse laser increases, and the temperature rise effect of the target is obviously enhanced with the increase of the auxiliary heat temperature, and the temperature rise effect produces a step when the auxiliary heat temperature reaches the melting point of the target.
