Just found this great site. Anybody can help me?

I am now doing a project, the part of it is to reconstruct a 2-D and 3-D image
from a hologram and project it to a surface. But I must use a high energy pulse
laser because we do care about the energy and the energy distribution on the
cross section plane and in the space. Our laser is Nd-YAG, green, 10Hz rep
rate, 30-1000mJ/pulse. We require the image size is <1x1cm. We don't have
holography equipment to record hologram, just want to use a hologram to
reconstruct a simple image.

1.Is there any company selling holograms which can be used in high energy
laser? 2-D or 3-D are all OK, I don’t care too much what the image is. The
simple, the better.

2. Probably I need the 3-D image depth down to tens of micron. Is that possible?

3. Because it is high energy laser, I have to wear a protective glass, how can
I view, detect and know if it is 3-D image?

4. Finally I may need to make any image I want, so the best way is probably to
use computer generated holograms. Is there any commercial or free software for
CGH?

Anybody can give me some suggestion? I appreciate it.
