Of my pictures that I've done with my laser, right now I'm liking the diffraction grating the best. I thought I'd share some of them, and maybe everyone will share their diffractoin grating pics too!

SenKat, that video was awesome! "The Light saber is in the chair" lol. I love the circular diffraction gratings. And here's another one for you Faithguy19. Two axis diffraction grating!

It's a longer exposure Kenom. Mine is probably maxing out at 5 mW. I was going to apologize for the overexposure on the last one, guess I forgot while I was resizing it. :-/ The Red one is much less than the Green, I'm thinking it's one maybe two mWs. I'm hoping my friend who works at Best Buy can help me get a DVD burner for pretty cheap so I can make a high powered red one. I also asked her to check to see if they have some broken ones that they'd be throwing away... I doubt they'll have DVD burners sitting around in the back, but if they do, and I didn't ask, I'll feel stupid :p Does anyone know of any alternatives to the NOVA diffraction gratings that gives a circular spread? I think it looks really cool, but $27 for a single piece of glass with a bunch of grooves cut in it, seems kinda high for me... I might give in though. I'll see if I can think of anything else to do with the diffraction gratings that will be interesting...

On a seperate note, I used a Canon Rebel XT for these shots, I have an IR remote, so I can just set the camera to where the laser will be in focus with the lights on, and then just hit the remote control button, and do my exposures, and then I hit it again to close the shutter. It's really nice when no one else is willing to be awake at 3 AM to take laser pictures with you :cool:

That's awesome Tropmonky! Now I want to play with some CDs I've got lying around! That makes me wonder how Tunnels will look if I use a CD as the mirror instead of... well, a mirror. Great idea! Now I'm gonna go play!

couldn't you just get one of those packs with the 1mw red and all those different difraction lenses, then put it in front of the greenie?

You can do that, but instead of making one of the picture it is supposed to, it makes a bunch of duplicates of the picture. So say the head you are using is an arrow, you put it in front of your greenie and it makes 8 arrows. I don't know why it does that with higer powered units but it does.
falchionsmight: Those are some awesome pictures and I think you should buy a laser from a company that gives out stuff for your pictures. So you could send them a bunch of pictures of the laser you bought from them and you could end up getting free lasers or supplies.

I always wondered if it would be possible to use those on a Greenie, just never tried. Good to know!


Here is another pic to.
