闲频 meaning in English

idle frequency
idle hour
idler frequency
idling frequency

In the case of type i down - conversion , the polarization of the signal and the idler photons will be identical , its direction being determined by the polarization of the pump
在第i类下转换情况下，信号光和闲频光的偏振是一样的，它们的方向是由泵浦光的偏振决定的。
In the previous studies , all - optical wavelength conversion is actuated by using light conversion and there has been no relevant report about the use of idle light
摘要在以往对全光波长变换的研究中，都是利用变换光实现波长变换，而利用闲频光的全光波长变换还没有相关报道。
It has been found that by simulating the effect of coupling attenuation on all - optical wavelength conversion , all - optical wavelength conversion by using both light conversion and idle light can be realized respectively by adjusting coupling attenuation under the condition of different pump light and signal light powers
文章通过模拟耦合器衰减对全光波长变换的影响，发现在不同的泵浦光与信号光功率条件下，调节辐合器衰减可分别实现利用变换光的全光波长变换和利用闲频光的全光波长变换。
