To my eyes that's the most pleasing and beautiful laser color I've seen! Lovely pictures also.

I determined last night my optimal exposure is close to 2 seconds, from about 15 inches away. Exposures < 1 second were successful, though dim. Unfortunately the battery scene was underexposed and too shaded to be interesting. However, a brilliant hologram of my glasses...

I don't have much experience making these holograms either. However if the laser is >50mW and closer than two feet from the hologram film I doubt you need more than a 2 second exposure. The LM317 based circuit I'm using in the laser is very very stable. See this topic on how to build this...

What sort of laser are you using? I've been using ~650nm red laser diodes. My laser is about 12-15 inches from the plate. Shining down at a 45 degree angle. Looks like this: The ~75mW laser in the picture yields a 1-2 second exposure time. It's critical that no vibrations be present in your...

You must see the hologram with your own eyes. Much more delicate and beautiful than the video. The magnifying glass works perfectly, for example. I had to use a fast f/ratio on the cam (low light), so I was unable to focus on the entire scene at once.

I don't have much experience with this either - these holograms are my first attempt. The development process is not difficult, nor very exacting. I followed the instructions included in the development kit. The difficult part is working in the dark. I used a illuminated watch to time things...

You're correct about the transmission holograms. I don't have much experience with the reflection holograms. For the few that I made I simply rested the glass containing the holographic emulsion on some coins and exposed to laser light. Of course there are many tutorials online, including...

I'm addicted to making these holograms now! It's not difficult. Here's a picture of my hologram exposure area: Everything rests on a board with bubblewrap under it. I've propped my brick laser pointer on the pot and the uncollimated output illuminates the hologram microcosm. For these...

PFG-03C emulsion may work for 445nm. Most of the hologram films are red or green sensitive. Otherwise there's no reason you could not use a 445nm laser.

Creating the hologram was much easier than I imagined. To create the transmission hologram a very simple work area was created: Objects being holo'd rest in front of a very high resolution film plate. Using light from my unfocused laser (75mW) an exposure of 1 second was all that was...

Last night I created my first transmission hologram of some marbles and other glass trinkets. The hologram film appears clear until shining an unfocused laser through it. You can see it's possible to adjust the focus at points within the hologram. QaUtKN-RPCE

Transmission hologram success! Here's my simple hologram work area, for developing transmission holograms: Everything is resting on the board, which in turn is laying on top of bubblewrap. I've propped my DIY laser 'brick' on the houseplant, and am aiming the uncollimated output towards the...

Holograms are not difficult to create. The most difficult and nasty part is developing the film. To create the hologram I placed the glass square containing the emulsion on top of coins and exposed it to an uncollimated laser diode for about 1 second, then developed. Area must be free from...

Here's my first successful hologram. This is a ~1 second exposure using ~75-100 mW DVD diode laser. Reflection hologram. I rested the film plate on top of some pocket change & items. Lens was removed from laser, which was located ~1 foot from film. The laser had been on for nearly 1/2 hour...

I'm very excited to finally see one of these laser diodes in action. It's a lovely color, as can be clearly seen in the pictures. Hope to add one of these to my laser collection eventually.

Thanks for putting this topic together. I'm still waiting to add a green direct laser diode to my collection. It seems they've been talking about these devices for years now, however no diodes have been seen outside of paper/lab. I suspect they are more difficult to fabricate than is admitted...

For grit and graphic effect, it must be #7. Galactica thruster.

Re: BEAMSHOT COMPETITION! w/ prizes :) anyone can enter (deadline 11/18)! 589nm is a lovely color, and that's a gorgeous beam picture! Tis unfortunate only very expensive, inefficient and fragile crystal lasers can produce that beautiful color. At least it's available as a pointer. It would...
