进行了使用还原剂 (R) 从氧化镁 (MgO) 激光诱导生产镁 (Mg) 的实验。在这些实验中，连续波 CO2 聚焦激光聚焦在氧化镁和还原剂的混合物上。聚焦激光的高功率密度导致高温和还原反应，从而产生镁。将所得蒸气收集在铜板上并根据镁沉积效率进行分析。测得各种还原剂（例如 Zr、C 和 Si）的沉积效率分别为 60、9.2 和 12.1 mg/kJ。发现相对于其相应的反应化学计量过量添加还原剂是大多数进行的激光诱导反应的最佳条件。此外，利用太阳能泵浦激光配合还原剂生产镁，可减少CO2排放，生产镁能效高、产量大。
Experiments for laser induced production of magnesium (Mg) from magnesium oxide (MgO) using reducing agents (R) were conducted. In these experiments, continuous wave CO2 focused laser is focused on a mixture of magnesium oxide and reducing agent. High power density of focused laser leads to high temperature and the reduction reaction resulting in Mg production. The resultant vapor is collected on a copper plate and analyzed in terms of magnesium deposition efficiency. Deposition efficiencies with various reducing agents such as Zr, C, and Si have been measured to be 60, 9.2, and 12.1 mg/kJ respectively. An excess addition of reducing agent over their corresponding reaction stoichiometric amounts is found to be optimum condition for the most of performed laser induced reactions. In addition, utilizing solar-pumped laser in Mg production with reducing agent will reduce CO2 emission and produce magnesium with high-energy efficiency and large throughput.
