摘要
为进一步提高氧碘化学激光器效率,提出一种不改变激光器结构,仅变换主副载气的方法。在增益区长度为11.7 cm的激光器上进行实验,以N2, Ar和CO2做为氧碘化学激光器的主载气或副载气,对激光器的输出功率和化学效率进行了研究。实验结果表明,平均分子质量改变对主副气流的混合是有利的,因而可以提高激光器的输出效率。当N2为主载气,Ar为副载气时,激光器输出功率和化学效率最高,分别达到3.09 kW,30.2%。
Abstract
To improve the output power and chemical efficiency, a new method is put forward, which requires no notable change in the configurations and uses different gases as buffer gas. Some experiments are done on chemical oxygen-iodine laser (COIL) with an 11.7 cm gain length. When N2, Ar and CO2 are used as the primary and secondary buffer gases, change of the average molecular weight promotes the mixing between the primary and secondary gases. Experimental results confirm the possibility of improving the chemical efficiency. When N2 is used as the primary gas and Ar as the secondary gas, the highest output power and chemical efficiency are obtained as 3.09 kW and 30.2%.
