【摘要】：激光驅(qū)動(dòng)飛片技術(shù)具有產(chǎn)生的飛片速度高、成本低、裝置簡(jiǎn)單等傳統(tǒng)動(dòng)高壓加載技術(shù)無(wú)法取代的優(yōu)點(diǎn).隨著激光技術(shù)的發(fā)展,利用高功率激光脈沖發(fā)射高速飛片受到越來(lái)越多的關(guān)注.本文介紹了在神光Ⅲ原型裝置上開(kāi)展的激光驅(qū)動(dòng)高速飛片實(shí)驗(yàn)研究.利用納秒短脈沖和納秒整形長(zhǎng)脈沖,設(shè)計(jì)并開(kāi)展了幾種不同方式加速飛片的實(shí)驗(yàn)研究,成功獲得了10 km·s~(-1)的固態(tài)鋁飛片和50 km·s~(-1)超高速度的復(fù)合金屬飛片,而且飛片具有良好的平面性和完整性.對(duì)實(shí)驗(yàn)的物理設(shè)計(jì)、技術(shù)途徑和數(shù)據(jù)結(jié)果進(jìn)行了比較全面的分析,為進(jìn)一步開(kāi)展激光驅(qū)動(dòng)高速飛片相關(guān)實(shí)驗(yàn)研究提供了思路,同時(shí)也證明了神光Ⅲ原型裝置在激光驅(qū)動(dòng)高速飛片實(shí)驗(yàn)研究方面有著巨大的潛力.
[Abstract]:Laser driven flyer technology has the advantages of high speed, low cost and simple device, which can not be replaced by the traditional dynamic high pressure loading technology. With the development of laser technology, more and more attention has been paid to using high power laser pulse to send high speed flyer. This paper introduces the experimental research of laser driven high speed flyer on Shenguang 鈪，
