针对激光在中性盐溶液中的传输特性及其浓度和温度的影响,基于溶液对激光吸收、散射的理论分析,通过测试实验得到不同浓度、温度下,配制各异的氯化钠和硝酸钠盐溶液对可见波长532nm、红外波长1064nm激光的衰减系数,结果显示,激光在分析纯盐溶液中的传输特性与纯水相近,浓度的影响微弱;激光在工业盐溶液中的衰减明显,衰减系数与浓度呈线性关系;30-40℃范围内温度对钠盐溶液的影响因子为比纯水高出1~2个数量级;可见激光在中性盐溶液中的衰减以散射作用为主,而红外激光仍以吸收为主。
Aiming at the laser transmission in neutral salt solution and its influence on concentration and temperature, based on the theoretical analysis of laser absorption and scattering from solution, different concentrations of sodium chloride and sodium nitrate were prepared under different concentrations and temperatures The results show that the transmission characteristics of laser in pure salt solution are similar to that of pure water, and the effect of concentration is weak. The laser attenuation in industrial salt solution is obvious. The attenuation coefficient And the linear relationship between the concentration of 30-40 ℃ temperature sodium salt solution than pure water higher than 1 to 2 orders of magnitude; visible laser in the neutral salt solution to the scattering of the main, and infrared Laser is still the main absorption.
