陡沿脈沖
英文
steep front pulse-
We apply the agrawal ' s theory model of soa, and study the temporal characteristics of the output pulse for input picosecond optical pulses with different sharpness edges passing through a semiconductor optical amplifier, and find that the peak power and the pulse width of the output pulse depend on the input pulse peak power, the sharpness degree of the input pulse edge and the bias current of soa
本文應用agrawal的關于soa理論模型,詳細研究了具有不同陡峭邊沿的皮秒超高斯光脈沖經soa后的時域特性的變化,發現輸出脈沖的峰值功率、脈沖寬度與輸入脈沖的峰值功率、輸入脈沖邊沿的陡峭程度以及soa的偏置電流密切相關。At present, signal pulses produced by directly modulated laser diodes have been used in optical fiber communication systems. the experiment reveals that the optical pulses from directly modulated laser diodes are far from gaussian and have near - rectangular temporal profiles with much sharper leading and trailing edges, and then a super - gaussian model, which assumes that an incident optical pulse has a super - gaussian profile, may be more suitable
但在實際的光通信系統中,人們常採用由直接調制半導體激光器產生的光脈沖作為信號脈沖,而實驗結果表明這種脈沖具有比高斯脈沖更為陡峭的前沿和后沿,其脈沖形狀更接近於超高斯分佈,並且通常還帶有一定量的啁啾。The optimum intervals between the two pulses is about 1. 7 in our simulation which is much longer than the commonly cited value 1. 5. 3. in the sm - lwfa simulation, we turned our attention to the wakefield generation and electron acceleration driven by the " self - modulated instability " and " side stimulated raman scattering "
我們首先提出「三角脈沖激發尾流場加速電子」的方案,利用「三角脈沖」平緩的上升沿激發「受激raman散射」預加熱電子,其陡峭的下降沿激發尾流場可以使更多的電子被「捕獲」 。Firstly, the paper discusses the characters, principles of excimer laser, and study on pulse discharge process. secondly, for the purpose of designing excimer laser, i spent a lot of time to researsh and finish electrode designing, reducing circuit inductance, spark gap designing, ns discharge, uv preionization, glow discharge
本論文首先對準分子激光特點,原理,脈沖放電進行了評述,其次,以試制xecl準分子激光器為目的,探索並完成了電極設計、迴路電感減小方法、火花開關設計、 ns陡前沿放電、紫外預電離、輝光放電、脈沖功率技術研究。The pulse - peek sampling and adc module is able to catch a single and very narrow pulse in order to sample its peek value without being influenced by other pulses or noise. the pulse - peek sampling and adc module can also adapt itself to different rising edge of pulses, so it can scale different types of explorers made by our research institute
X射線探測器定標分析系統的前端脈沖峰值採集及其轉換電路能夠實現單個快速脈沖的捕捉及對不同脈沖上升沿陡緩的適應,它對不同傳感器的放大信號特徵都有很好的適應性,對脈沖峰值采樣的結果具有很高的精度。In the case of ultrashort laser pulse, the effect of finite pulse length is anlyzed, and self - steepening in the front of the pulse will occur when only relativistic nonlinearity is considered
同時,對于超短脈沖傳輸,分析了有限脈沖寬度效應對傍軸方程的修正,當只考慮相對論性非線性效應時將會引起激光脈沖前沿自陡峭。分享友人
