中文摘要：

为了研究一种新型固-液混合型的流体激光材料作为激光增益介质应用的性能,研究了其散射损耗随折射率及温度的变化规律。搭建了行波放大器实验平台,进行了该新型流体激光材料和钕玻璃固体激光材料的性能对比。实验表明,该流体材料具有典型的激光增益特性,然而其散射损耗对介质折射率和温度的变化比较敏感;在固-液相折射率匹配的条件下,散射损耗小于0.0047 cm-1。实验结果表明,通过对折射率匹配的控制,该流体激光介质可以将散射损耗控制在合理的范围内以实现显著的激光增益,具有向高能激光体系发展的前景。

英文摘要：

The scattering loss of a new mixed fluid state laser material varying with refractive index and temperature is studied experimentally.A platform of laser amplifier is established,on which the laser performance of the new material is shown by a comparison between the fluid state laser material and Nd-glass solid laser material.Experimental results show that the fluid state laser material possesses typical laser gain,but its scattering loss is sensitive to the variation of refractive index and temperature.The scattering loss can be controlled under 0.0047 cm-1 with accurate refractive index matching.The results above indicate that the method of refractive index matching is able to ensure an acceptable scattering loss of this new type of fluid state laser material,so this new material has a potential ability in high power laser systems.
