low power laser meaning in English

低功率激光器

The main content of the work are as follows : developing a compact dynamic light scattering instrument with low power laser
本研究工作主要参与完善改进了一台本实验室自行研制的小型低强度激光光子相关谱仪。
Compared with current instruments , the setup can decrease disturbance of disorder radiation by using double layer refractive index sample matching vessel , and it can increase collecting and transmitting efficiency of radiation by adopting single mode fiber with gradient refractive index lens . with a low power laser , the sample has a low scathe , and the laser and the measurement system can be integrated conveniently
与现有的同类型仪器相比，该仪器采用双层折射率样品匹配池减少了杂散光的干扰；采用带梯度折射率透镜的单模光纤接收、传输散射光信号提高了散射光的收集传输效率；用低强度的激光避免了对样品的辐射损伤，同时可以使激光器和系统集成在一起，整个系统小型实用。
