Influence of pulse duration and interaction length on transient sbs induced damage 誘導(dǎo)的激光超聲破壞效果的影響
When the interaction length or gain coefficient is changed , the sbs threshold is changed , and the intensity value of optical limiting is altered 當(dāng)改變相互作用長度或者介質(zhì)增益系數(shù),即可以改變受激布里淵散射的產(chǎn)生閾值,進(jìn)而改變輸出脈沖空間限幅的幅值。
The influence of msfvw bandwidth on the diffraction efficiency is also considered . for the nonuniform bias magnetic field of u - type parabola profile , when the msw frequency is less than the cut - off frequency at the edge of mo film , the effective mo interaction length reduces . the edge cut - off frequency is determined by the maximum of the nonuniform field 對于拋物型分布(開口向上)的偏置磁場,當(dāng)激發(fā)靜磁波的rf頻率小于邊緣截止頻率時,磁光作用的有效長度減小(與靜磁波頻率有關(guān)) ;邊緣截止頻率由不均勻磁場的最大值決定,靜磁波的下限截止頻率由不均勻場的最小值確定。
