摘　　要：烟火泵浦是激光器小型化、便携化的一种解决方法。研制了一种用于钕玻璃激光器泵浦源的化学试剂,其主要成分为金属粉和碱金属含氧酸盐。设计了烟火泵浦钕玻璃激光器实验装置,激光器采用平-凹腔结构、紧包型侧面泵浦,输出镜反射率98%,钕玻璃棒尺寸8 mm×100 mm。采用A,B两种配方的泵浦源进行出光实验,A配方得到了波长为1053 nm能量为29 mJ的激光,B配方没有出光。分别计算了两种泵浦源的阈值辐射强度,并与测量得到的药剂辐射强度平均值比较。A配方所提供的辐射强度2.68×104W.sr-1,大于阈值2.37×104W.sr-1;B配方小于阈值,未能出光。这与实验结果吻合,证明烟火泵浦方法可行。Pyrotechnic explosion pumping method is one of the solutions to make miniature and portable laser. A chemical reagent used to pump Nd glass laser was prepared. The main ingredients of the reagent were metal powders and alkali metals＇ oxysalts. The experimental apparatus of pyrotechnically pumped Nd glass laser was designed. The laser consisted of a φ8 mm× 100 mm Nd glass rod tightly encircled with pump sources by the side. The resonator contained a high reflection plane mirror and a concave mirror of 98% reflectivity. Output experiment used two reagents A and B with different near-infrared radiation intensity, reagent A output 29 mJ laser beam with wavelength 1 053 nm, and B didn＇t output laser, Pumping radiation intensity thresholds of the two pump sources were computed. Reagent A gives 2.68×10^4 W · sr^-1 , higher than the threshold 2.37 × 10^4 W · sr^-1 , and B gives an intensity lower than its corresponding threshold.
