Development of milliwatt ultrasound power measurement system 毫瓦(MW)级超声功率测量系统的研制
The nonlinear Raman scattering in the benzene liquid-core optical fiber has been studied in this paper, using 2 milliwatt CW He-Ne laser as light source. 用2毫瓦(MW)输出的连续Ne-He激光器作光源来研究苯液芯光纤中的非线性拉曼散射效应。
We have firstly developed the all fiber femto-second laser, but its average output power is only tens of milliwatt. With the development of cladding pumped technology, it is the efficient way to amplifying the output power. 在国内我们已经首先研制成功了全光纤飞秒激光器,但平均输出功率只有几十毫瓦(MW),包层泵浦技术的成熟,无疑给其进一步放大功率提供了技术保障。
