The diode is a part inside the module. The module is everything but batteries.

I am part of the 99.9 percent of the human population who plays with lasers and have no practical function for us so I shouldn't feel immature for wanting to replicate a star wars light saber. I think about 20 laser diodes can be stacked in two offset and off sized rings to make one hell of a...

I'm new here and don't know much but from staring at pricing and parts I can tell the lasers still work without the container and it has no electrical function. So I believe you can machine one.

I am looking on ebay for about 20 lasers but the numbers vary very widely. As far as I know, the (nm) is how bright it is and the (mw) is how hot it is. Am I right?

I would not have bet money that they could do so much with colors. I was imagining a cone that could take in light from all around the rounded edge and send it straight out of the flat end. I see that I assume to much with optics and light but let me ask one who may know if it would be possible...

Thank you, I will look into filled aperture combining. My curiosity was why someone hasn't put a dozen or more diodes into a hand held device since they are so small.

Let me clarify, every picture I see of combining multiple beams, it is always at a 45 degree angle. I'm wondering if the beams can be ricocheted at a steeper angle like 1, 2, or 3 degrees?

Sketch of what I had in mind.

Hi, I am new here and I'm not even close to knowing anything about lasers but I have a serious curiosity if someone can tell me. Is it possible to run multiple beams ( 10 - 20 ) through one lens or PBS cube at about a one degree angle without losing the width of the beam?
