1 Now, non-volatile holographic storage to maintain information has been put into use for a long time in this photorefractive crystal. （該句沒有主謂語，我加了has been put into use）
2Recently, the usage of （把using 改為the usage of）two coherent recording beams in the presence of a sensitizing bean(這里應(yīng)該是beam 吧) with good nonvolatile holographic storage was achieved in doubly doped Ce:Fe:LN crystals.
3 The concentration of Mg2+  in  the melt changed from 0 to 3mol% (0,1,2 and 3mol%) (去掉was,另外你把 from 寫成form了)
4 The unpolarized ultraviolet-visible (UV-Vis ) absorption and  infrared  transmittance  (IR) (前面兩個單詞的首字母縮略詞不是IR吧？這兩個的意思不一樣哦) spectra were measured  to  analyze (analyzed 去掉d) the defect  structure of  these crystals,  ranging  from300-900nm  to 400-4000cm-1.respectively.(把a(bǔ)nd 改為to, range from...to...)
5.The  effective UV-Vis and  IR  range in（將fro 改為in）  later  discussion  were  from  360-600nm and 3400  to  3560  cm-1.
就這幾個單獨的句子，又沒中文，有點難懂哦，我不是你這個專業(yè)的，只能看看語法什么的，也只能改這么多咯，不知道改的對不對，如果有不對的地方請指正。我把改了的地方給你標(biāo)記出來了，因為以前別人也是這么要求的

贊一下
