烟火抽运激光器以烟火化学反应发出的强光作为光抽运源,火药剂量与排布方式直接影响激光器的出光性能。通过考察药剂量从12～48个之间变化时激光能量的变化,以及比较两种火药排布方式,得出参加反应的化学药剂量及药剂布局影响激光器出光能量的规律。当药柱量在21～30之间时激光能量较高;两种对称的布局方式中,药柱分布集中、使用电阻丝少的方式有明显优势,药柱分布分散、使用电阻丝多的方式得到的激光能量总体较低。将24个药柱平分作3串,均匀分布在石英管周围,得到1.003 J的激光能量,是早期工作中得到激光能量的30倍,药剂量仅为1/4。
Pyrotechnic pump laser to fireworks emitted by the chemical reaction of light as a light pumping source, the powder dose and arrangement directly affect the performance of the laser light. By investigating the change of laser energy when the dosage is from 12 to 48, and comparing the arrangement of two kinds of gunpowder, we get the law that the amount of chemical agents and the drug layout that participate in the reaction influence the energy of the laser. The laser energy is higher when the medicine amount is between 21 and 30; among the two symmetrical layout modes, the medicine column is concentratedly distributed, and the method of using less resistance wire has obvious advantages. The medicine column is distributed and dispersed, and the resistance wire is used in many ways The resulting laser energy is generally low. Dividing the 24 drug cartridges into three equal parts evenly distributed around the quartz tube yields 1.003 J of laser energy, which is 30 times the amount of laser energy obtained in earlier work and only 1/4 of the dose.
