We anticipate that we may make optical limiting devices which are useful both on pulse laser and on continuous laser 我們預(yù)期可以利用它們制成對(duì)連續(xù)光和脈沖光都有限幅效果的光限幅器材料。
Abstract : this paper studied the damage effects of sic fiber reinforced al matrix ( sic / al ) composite irradiated by a highpower continuous laser 文摘:研究了鋁基碳化硅纖維增強(qiáng)復(fù)合材料在連續(xù)波強(qiáng)激光輻照下的破壞效應(yīng)。
Two research groups , one at the university of california at los angeles and the other at intel corporation , have recently reported success in making silicon emit continuous laser light 日前有兩個(gè)團(tuán)隊(duì)宣布已能使矽材料持續(xù)發(fā)出雷射光,分別是美國(guó)加州大學(xué)洛杉磯分校和英特爾公司。
The factual models of the composite irradiated by a high - power continuous laser mainly included the melting and vaporization of al , and a structure destroy caused by the degradation of the reinforced fiber which had reacted with the al matrix 強(qiáng)激光輻照使金屬基復(fù)合材料產(chǎn)生的主要效應(yīng)是基體的熔融、汽化和纖維與基體反應(yīng),這些效應(yīng)是造成金屬基復(fù)合材料強(qiáng)度大幅降級(jí)從而導(dǎo)致材料結(jié)構(gòu)破壞的直接原因。
The technical breakthroughs in growth of nd : cngg had been made . in particular , continuous laser operation was achieved from nd : cngg pumped by ld . when the crystal wafer was end - pumped by one bar of ld with 807nm wavelength , the cw laser output power of 123 . 1 mw was obtained with slope efficiency of 22 . 3 % 本論文用自動(dòng)化熔體提拉技術(shù)成功生長(zhǎng)出< 111 >方向的直徑25mm以上,長(zhǎng)度80mm以上的平界面無(wú)核心nd : cngg單晶,確定了晶體結(jié)構(gòu)和物相,測(cè)量了晶體的光譜性能,晶體消光比達(dá)到34db ,晶體生長(zhǎng)技術(shù)有新的突破,實(shí)現(xiàn)了連續(xù)激光運(yùn)轉(zhuǎn),用單支807nm半導(dǎo)體激光二極管端面泵浦該晶體片子,在國(guó)內(nèi)首次獲得123 . 1mw的1 . 062 m連續(xù)激光輸出,斜效率達(dá)22 . 3 % 。
