<![CDATA[I use 5W of 532 and frequently go 60-90sec for a basic
transmission 8x10. I don't think 5mw is enough to let the
photopolymer know you're there.]]> 216.175.118.162

<![CDATA[Lon Moore,
I saw that you use 5W of 532. What laser(type and name of
company) do you use to get this power? Is it continuous or
pulsed? Any help would be greatly appreciated.
Thanks

Trying going to the website www.amazing1.com/
laser.htm. This is the Information Unlimited website. It
also sells industial class 4 high power lasers. Have
fun Hiram.]]> 208.40.48.35

<![CDATA[P.S. The beem at 532nm is continuous at 5mw. They
also have high power ones at the same wavelength]]> 208.40.48.35

<![CDATA[as i work for dupont, i can tell you with assurity that
pointing a 5mw laser pointer at a piece of photopolymer
paper will have no effect, regardless of using 706 or any
other film.
for lon and hyrum, have you tried using any other
frequency than 532nm? if so, which and what were the
results?

<![CDATA[where do you get the polymer from ?
They are not supposed to be selling the stuff.

<![CDATA[It is pretty easily made I am told. Jeff Blythe has a good
recipie. I am not sure if it is on his web site. Jon Dark
gave some useful hints into making it in some posts to the
yahoo holography forum.
Lon is a licenced Dupont photopolymer user.]]> 64.170.194.10

<![CDATA[I am a researcher at MIT investigating holographic
interconnects for computers. We have been using a Polaroid
photopolymer (now Aprilis I think) with pretty decent
results. We have tried to get information (specs and
pricing) on the Dupont material without much luck. Any
information on the Dupont photopolymer would be much
appreciated.
Thanks,

<![CDATA[I don't really follow photopolymer but I did hear at
SPIE '03 that Dupont is no longer offering their
photopolymer to the public because of an exclusive security
agreement with the German government.]]> 67.113.4.182
