把激光脉宽调整到与吸收颗粒的热弛豫时间一致可以避免热副作用,可对所选细胞产生选择性处理。
Adjusting the pulse width of the laser to the thermal relaxation time of the absorbing construction can avoid thermal side effects and facilitate a selective treatment of the selective cells.
通过脉宽为周期量级的超快强场激光脉冲与惰性气体原子的极端非线性相互作用,能够产生单个的阿秒量级的极端远紫外光脉冲。
Single isolated attosecond (as) extreme ultraviolet (XUV) pulses can be generated via the nonlinear optical interaction between intense few-cycle laser fields and noble gas atoms.
由于脉宽的差异,这两类激光脉冲与固体靶的相互作用机制会有本质不同。
Because of the difference of the beam wide, the two interaction mechanisms have intrinsic differences.
考虑了光源初始啁啾的作用 ,推导出均方根脉宽的解析表达式 ,分析表明 :二阶偏振模色散对脉冲展宽的作用与群速度色散及啁啾有关 ,一阶偏振模色散的作用则与这两者无关。
Taken into account both second order dispersion and SPM in the abnormal-dispersion region of single-mode fibers, we obtained the expression of chirp induced by GVD and SPM.
但作用距离的分辨率却与发射脉宽成反比,脉冲宽度越窄,则频谱越宽,测距越精确。
But the resolving power of radar is in inverse proportion to the pulse-width. The pulse is the narrower in width , then the wider frequency spectrum is, it is the more accurate to find range.
