摘要

针对目前碘激光用化学能作为泵浦源

体积大

易产生有毒物质

且运行时间短

影响其应用范围等问题

本文提出利用碘等离子体产生激光辐射的设想。建立了碘1315 nm受激辐射的等离子体产生模型;通过对泵浦光功率密度与离化电子数密度、自由电子温度等的理论计算

确定了本实验条件下的最优实验参数范围;然后在理论计算的参数范围内

用Nd∶YAG激光器的二倍频532 nm激光泵浦固体碘产生等离子体

并采集其荧光发射谱;最后

通过拟合碘等离子体光谱扫描结果得到发射谱的中心波长位于1 313 nm

谱宽为1.182 nm。研究结果显示

通过激发等离子体的途径实现碘原子受激辐射的构想是可行的。

Abstract

As the iodine laser is pumped by chemical energies at present

it shows a larger cubage

shorter running time and produces toxic materials easily. These disadvantages limit the application of the iodine laser. To meet the requirements of the miniature

pollution-free and high power iodine laser in practical applications

a new idea for iodine laser production was proposed in this paper. Firstly

a plasma generation model was established to produce a 1315 nm iodine laser stimulated emission.To obtain the optimum parameter range of an experiment in our experiment conditions

the power density of pump light

ionization electron density and the free electron temperature were calculated. Then in the optimum parameter range calculated

the iodine plasma generated by a single longitudinal mode second-harmonic Nd∶YAG laser (532 nm) was detected by a spectrometer to obtain its fluorescence emission spectrum. Finally

the fit result for the signal obtained in the experiment shows that the signal peak is located at 1313 nm with a bandwidth of 1.182 nm. The results reported here demonstrates the possibility that the iodine plasma is acted as laser media to produce stimulated emission.
