its repeated frequency was 1khz with 20us width of pulse ?第四部分是對線性調(diào)頻信號源測試和評估。
the article quantificational studies the relation between gas quantity and voltage amplitude and pulse width of pulse supply power driving valve 文中對該類型閥門特性之一的進氣量與所施加的脈沖電壓幅值和脈寬的關(guān)系進行了定量研究。
in addition, the time-width of pulse also influences hhg . to some extent the spectrum of hhg will become be tter when the time is prolonged 另外,激光脈沖時間的長短也會影響到高次諧波的性質(zhì),在一定范圍內(nèi),隨著脈沖時間的加長,電離率逐漸增大,譜線結(jié)構(gòu)也越來越明顯。
it has been presented in this dissertation that using model of q modulated er-glass laser, through replacing typical number of er-doped fiber and single mode fiber into the model, then the theoretical model of self-q-switching by sbs was established . by emulating experiment, the peak value of output power, repeating frequency, width of pulse have been calculated . the data was calculated repeatedly when the length of er-doped fiber changing 將摻鉺光纖和單模光纖的典型值數(shù)據(jù)代入該模型中,進行仿真實驗研究得出sbs自調(diào)q光纖激光器輸出峰值功率、脈寬、重頻等數(shù)據(jù),并在改變摻鉺光纖長度的情況下,再次進行仿真實驗,對上述輸出結(jié)果進行了分析。
