Promised these for a while, finally got around to it. I shortened the tube and now I call it the L3 pocket rocket. Absolute shit runtimes (~3m at turbo or untill overheat)

Anyone here have a LPM and 445nm diode? I have some strange lenses that came out the PJ with the m140 diodes. They seem similar to the g series lense as they are both single element but mine do not have a mounting rim. I'd be happy to send a few to anyone who wants to provide some graphs or...

I've been gone for a while! Thought I should make a new post here and meet some new members!

Im working on a short presentation for class and I chose resonance, specifically how resonance applies to lasers. After wikiing laser resonance and reading up on the basics, I still have no idea what is going on. What determines the wavelength? Where does resonance apply in lasers? It is a...

I want to get 3x laser hosts that take either a 12mm module or a 5.6mm diode. I would like it to be able to fit a 17mm driver and take a 18650 driver. Basically anything along the lines of the ultrafire wf501b kit. I want it to be ~30$ for all three. I also want to get 3x 5.6mm modules with a...

It just started but in South Africa there is a partial solar eclipse and some guy is talking about eclipses while it happens. watch it here! WATCH LIVE SUNDAY @ 12:30 am ET: Slooh Webcast of Partial Solar Eclipse

Supfire L3 - XM-L2 - 1x or 2x 18650/26650 Ive used this as a host for a high power flashlight build and it can take quite a bit of heat. Its similar to the xml t6 host everyone here uses. (kinda weird as the led is the cree xml t6, not the flashlight) Anyways would it be possible to make a...

I've always thought if you put a m140 diode in one of DTR's module and added a 3 element glass lens you would a round beam far away. As I continued to browse through the forums, ive noticed people posting pictures of a flat beam and taking about using prism pairs to make the beam rounder. If I...

AUG 23 EDIT Im out of diodes, will update title if anythng changes. =================================================== JUL/20 EDIT HUGE price drop, now $17 will give a discount for buying multiple! You can pm me or buy via ebay...

I was talking to AgentMcBaine and he gave me the idea of a LD giveaway. I have a bunch of diodes and figured a giveaway would be a nice way to start at LPF. Heres a link to the diodes https://drive.google.com/open?id=0BwauATVVJAa7U3F1MHU5OUNjdDg Im ending this giveaway on Thursday September...

I found out something intresting, I think It belongs in this subforum. When you take apart the projector, there is a glass lens matrix(24 glass lenses on a single glass rectangle). This lens is pretty much useless in a laser build but if you hold the lens up to a camera, you can get some pretty...

Anyone use XHP70's? Im wondering how you guys are driving your leds as they use 6 or 12v. Im using mtnelectronics FET direct drive driver. Anyone else experiencing over heating problems in their builds?

I saw this 445nm 450nm Laser Protective Goggles | eBay and thought that an OD of 6+ sounded kinda weird. Is this real?

I was looking at the g2/1 lens and also the 3 element glass lens for my first high power laser with the mtype m140 laser. Should I go with the g1/2 or the 3 element?

Hey, newbie here. Just opened up my first m140 projector. I have a few mtype and atype m140's I've heard people talking about how atype a140s are true 455 while the a and mtype m140s are 450. Is there any real difference and is it noticeable? How do the wave lengths compare between the a and m...
