模间隔 meaning in Chinese
mode spacing
Examples
- The prerequisite of actively mode - locked fiber laser stable work is that the modulation signal frequency must be the integral multiple to the cavity resonance frequency
主动锁模光纤激光器稳定工作的前提条件之一是调制信号频率应为腔内纵模间隔的整数倍。 - Numerical simulations show that : ( 1 ) owing to the temperature variation resulting in the change of the refractive index of both the semiconductor medium and the fi ber , and further inducing the shift of the longitudinal modes of the fgesl , the lasing wavelength of the fgesl has a shift tendency to longer wavelengths with the increase of the temperature ; the mode hopping happens for a short external cavity and disappears for a long external cavity
数值模拟的结果表明:由于温度变化造成半导体介质和光纤的折射率发生变化从而导致fgesl的纵模发生移动，因此fgesl的激射波长随着温度的升高将存在向长波长方向发生移动的趋势，对于短外腔， fgesl的纵模间距较大，半导体介质折射率随温度的变化程度大于光纤折射率随温度的变化程度，因而存在模式跳跃现象;对于长外腔，由子fgesl的纵模间隔很小，因而不存在明显的模式跳跃现象。 - In this paper , a new theoretical model is established for optical fiber pumped by broadband laser . using the new model , we have analyzed the influence of longitudinal - mode number , bandwidth and line - width of pumping source on sbs reflectivity , and pointed out the monochromaticity of pumping laser has obvious affect on optical fiber conjugator
成功解释了激光线宽、纵模间隔与数目对光纤中sbs过程的影响，并通过数值计算分析了sbs阈值、反射率、相对稳定性、保真度等性能参数随着注入激光能量、脉宽以及光纤长度、芯径的变化趋势。
