  9. In this thesis, we used the q - switched nd : yag laser pulse focused by lens to pump the cr ~ ( 4 + ) : mg _ 2sio _ 4 crystal, with the pump laser pulse duration and energy of 30ns and 50 mj separately, and got the laser pulse with center wavelength, pulse duration and energy of 1. 22 m, 8. 2 ns and 10 mj on the best work condition. on the base of zhangguowei s approximation about gain - switching and the parameter of cr ~ ( 4 + ) : mg _ 2sio _ 4 crystal, we calculated the time characteristics of cr ~ ( 4 + ) : mg _ 2sio _ 4 laser pulse with rate equation by numerical method, obtained the conclusion that the laser pulse duration is only related to the pump energy and cavity length : the larger the pump energy is, the narrower the pulse duration is ; the longer the cavity is, the wider the

    本論文採用調qnd : yag脈沖激光通過透鏡聚焦后縱向抽運cr ~ （ 4 + ） : mg _ 2sio _ 4晶體，抽運光脈沖寬度為30ns 、能量為50mj ，在較佳工作條件下得到了中心波長為1 . 22 m 、脈寬為8 . 2ns 、能量為10mj的激光脈沖;並在張國威分析增益開關時間特性的近似法基礎上，結合實際的cr ~ （ 4 + ） : mg _ 2sio _ 4激光器的相關參數，從速率方程出發，用數值計算的方法更為精確的模擬了cr ~ （ 4 + ） : mg _ 2sio _ 4激光器輸出激光脈沖的時間特性，得出了激光脈寬只與抽運能量、腔長有關的結論，即抽運能量愈大，脈寬越窄;腔長越長，脈寬則愈寬。
