載波包絡 的英文怎麼說
中文拼音 [zǎibōbāolào]
載波包絡
英文
carrier envelope-
Shapes of pulse envelope are found to have some effect on the degree of phase influences. dependence of single - cycle pulse ( scp ) energy on the carrier phase has been studied for gaussian, lorentzian, hyperbolic secant and sine shapes respectively, which shows that these energies can be expressed in the same form. phase effect on pulse with gaussian envelope is the first to show, then are hyperbolic secant and lorentzian pulses, and sine the last
包絡對載波相位的作用范圍也是有一定影響的，我們對高斯、洛侖茲、雙曲正割和sinc四種不同包絡的脈沖，研究了單周期脈沖能量隨載波相位的變化規律，發現以上四種脈沖的歸一化能量均可在形式上用同一表達式表示，並發現對于這四種不同包絡的脈沖，高斯脈沖相位的作用最早體現出來，然後是雙曲正割和洛侖茲脈沖， sinc脈沖最遲。Calculations indicate that the carrier phase takes effect till the time width of the pulse envelope becomes smaller than the period of the carrier oscillation, and the interpretation of this phenomenon is also presented. it is the difference between phase delay and group delay that causes the sliding between the carrier and the envelope
數值分析的結果表明，當脈寬小於光波周期時，相位的作用開始顯現出來，當脈寬比光波周期長時，載波相位的作用可以忽略，並分析了相位起作用的原因，用解析的方法說明正是相延遲和群延遲之間的差別造成了光載波在脈沖包絡下的滑動。With the development of few - cycle pulses ( fcp ), the phase shift of the optical carrier with respect to the pulse envelope becomes non - negligible
隨著周期量級激光脈沖的產生，脈沖載波及包絡之間的相對相位漂移逐漸成為不容忽視的問題。
