how to choose a dye for a given laser beam holography?
Posted: Sun May 14, 2006 1:36 am
Hi,guys
there have been lots of dyes to choose from for a given laser beam line holography.such as Methylene Blue trihydrate+TEA(or others photoinitiators) which was generally used to sensitize or match the Red laser beam,ErB or Ciba Irgacure 784 for a green laser line(514.5 or 532nm) application,etc.
I wonder to know is there any other dye or the direct initiator,specially used to make a photopolymer plate, to be existed or chosen for holography? what's the point to choose one of them for a given beam or one color appliction? is there any rule to obey?
hope someone can share some expriences with me,or recomend some available materials to me
best wish!
