以海藻酸钠溶液为研究对象, 利用激光诱导前向转移技术诱导溶液转移, 探讨激光脉冲能量、光斑直径、钛层厚度以及海藻酸钠溶液质量分数对液滴的直径和表面形貌的影响.实验结果表明, 当光斑直径为100 μm时, 液滴的直径更小, 且表面致密均匀且形貌清晰.极差分析显示海藻酸钠溶液质量分数、激光脉冲能量、光斑直径、钛层厚度对液滴直径影响的重要性递减.同时利用高速摄影仪拍摄激光诱导海藻酸钠溶液转移的过程, 发现激光诱导液体靶材转移过程中伴随着流体多相动力学行为.

An experiment research on the laser induced forward transfer of sodium alginate solution was carried out, and the effect of laser pulse energy, spot diameter, thickness of titanium layer and the mass fraction of sodium alginate solution on experiments of droplet diameter and surface morphology was discussed. The experimental results showed that when the spot diameter was 100 μm, the diameter of droplets was smaller, and the surface morphology was dense and clear. The range analysis showed that the mass fraction of sodium alginate solution, laser pulse energy, spot diameter and thickness of titanium layer are less important influencing the diameter of droplets. At the same time, high-speed camera was used to study the laser-induced sodium alginate solution transfer. it was found that the laser induced liquid target transfer process was accompanied by fluid multiphase dynamic behaviors.
