linewidths造句
例句与造句
- with increasing x, the intensities of the deep nni centers and their phonon sidebands become enhanced and their pl linewidths gradually broaden and shift to lower energies
一方面，得到了gapi.xn:混晶从低n组分下的nn.对中心的发光到高组分下形成杂质带的演变。 - abstract : we have studied the polarization beats spectroscopy with phase-conjugation geometry in a cascade three-level system . it was found that the accuracy for the energy-level difference measurement is determined by the homogeneous linewidths of the optical transitions . under the condition for the occurrence of beating, the frequency difference of the beat between two independent light sources could exceed the laser linewidth . the measurement accuracy for laser absolute frequency could reach the same order of magnitude as the laser linewidth
文摘:研究了级联三能级系统中的相位共轭极化拍频光谱术.发现其对能级差的测量精度决定于光学跃迁的均匀增宽.在符合拍频条件时，两独立光源拍频的频差可以超出激光线宽，激光绝对频率的测量精度可达到与激光线宽同一量级 - abstract : we have studied theoretically a beat effect in a four-level system due to fifth-order optical polarization, and considered the cases that the pump beams have either narrowband or broadband linewidth . we have found that the accuracy for the energy-level splitting measurement is determined by the homogeneous linewidths of the optical transitions . that is to say, this technique can achieve doppler-free precision in the measurement of the energy level splitting between two excited states which are dipolar forbidden from the ground state
文摘:研究了四能级系统中基于五阶极化的拍频效应，考虑了抽运光束为窄带线宽或宽带线宽的情形.发现其对能级分裂的测量精度决定于光学跃迁的均匀增宽.也就是说，这种技术在测量与基态是偶极禁戒跃迁的两激发态之间的能级分裂时，可得到消除多普勒增宽的精度 - It's difficult to find linewidths in a sentence. 用linewidths造句挺难的
