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.

The (nm) indicates the frequency (or color) of the laser light and the (mW) rating is the power.

The module is what holds the laser diode and you could machine your own but it is easier to purchase one. It not only holds the diode but it also holds the lens that is used to focus the laser. It also serves as a heat sink to help keep the diode cool.

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 light saber - laser pointer or could be reflected back. I got the inspiration from another blog at this link,

Hi, I am new, can anybody explain me what the laser module is ?

Laser module = laser diode + lenses + driver + cooler ?

So If you buy laser module, you need just batteries and any (good looking) housing (so you dont need driver, dont need lens) ?

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

I own a small machine shop in lynnwood wa.
I finely bit the bullet and bought a 445 1. watt diode
I all ready have a drawer full of greens mods and a
ton of red diodes , so I'm going to try my hand at miniaturization.

I'm going to try to "squish" it in to a 21mm 7/8" dim by 6 1/2" long
output will be quite low but Who cares it's white .

just wondering why some hasn't try this or they have
and found it to be not worth the effort to try and miniaturize these
sub assembles
I really like how smart , resourceful and honest experimenters are
on this form , and I appreciate and value your Input , advice.

PS just wondering what would you pay for a
good white laser provided it was small compact??
total out put 40-50 mw




Thanks

Rob

is there a kit with everything in one box without spending a mollion bucks ? im begining to understand the different caponents but still not sure if im pairing things properly. kind of wanted to do a blue-ray or a green of decent power. i dont want to build something so entry level its worthless after the oooh-aahhh factor wears off.
id like to be able to pop balloons and cut tape.

keep up the awesome work guys, and dont stop till you get a light-saber going ! :thanks:

Take a look at the Laser Pro Shop section, Jayrob for example offers some great kits, but there are a ton of other kits out there.
