Hey likewhat, sure I'd love some help, thank you! So info about the fiber: From: \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\ psplc.com/datasheets/jdsu/JU6300Series_041802.pdf \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\ Fiber core diameter...

Ah, but the problem is more fully explained in the optics post I submitted. My IR laser has no collimating lens and burns a 2mm wide "tear" rather than the neat cut I get with the red diode. I still can't find the right pigtail accepting collimating lens and even if I did, would need help on...

Sweet experiment setup idea thekanester! I too think it would be a great resource to have that information, perhaps someone here knows if it's been done before. Especially since I do not have, nor do I know where to get something that could measure reflection. Is a power meter exencive? Could...

So, I've got a 4 W IR laser diode (fiber optic with no pigtail collimator) and I'm stumped. I've been looking around for a collimator that will fit it at Thor Labs thorlabs.com/NewGroupPage9.cfm?ObjectGroup_ID=1340 and I've got two problems. 1) Can't find the right lenses with all the right...

Hello all! These seem like great forums! So, I was wondering if you could lend me a hand. I'm the creater of the 50 dollar laser cutter hack: instructables.com/id/Laser-cutter-start-slicing-stuff-for-under-50-dol and I have a question I think someone here knowledgeable in optics and wavelengths...

Oh, a member "bluefusion" on instructables told me that this was the ideal place to go to for information about lasers. He recommended me here because of my post: instructables.com/id/Laser-cutter-start-slicing-stuff-for-under-50-dol And I'm here because I've been interested in lasers ever...

Yep. New here too, I'm from Ann Arbor MI... ? Anyone from near the U of M umich campus? -bg
