Does anybody sell laser diode extractor tools nowadays? I know flaminpyro used to sell them but I guess he doesn't come here anymore. Multiple people have pointed me to DTR but I don't see any on his site. I really need a 5.6mm diode extractor, but I'd be also interested in 3.8mm and 9mm sets...

Hey everybody! I have a contact in China that has 495nm diodes and 488nm diodes apparently arriving shortly. This is a supplier that others have dealt with on LPF before. I think I am going to get some 495 diodes, so I wanted to see if anybody else wants to piggyback on my order. I'd need to...

The TEA nitrogen laser was one of the very first DIY laser designs to be built by many hobbyists around the world. Scientific American published plans for a simple N2 laser in the 1970s, and since then there have been many other iterations by hobbyists. This is a very easy build that I recommend...

I finally decided to post some footage of my huge ruby laser. The rod is a very large 1/2" diameter by 6.1" crystal and I'm using a large helical lamp running at about 13kJ per shot for the video. Considering all of the exposed high voltage contacts, this laser is really scary to use...lol. I...

Hey machinists of LPF! I'm looking to have a custom heatsink made for me. Basically I'm looking for something that holds 7x AixiZ modules, with a flat bottom. The exact dimensions I'm not super picky about. I'd like the AixiZ modules as close together as possible without ruining any structural...

Not sure where to put this but I'm looking to take on a large knife-edging and beam combing project. As you may guess, it's for a huge laser gun. :p My 200W laser bazooka had terrible beam specs, but with proper mounts and optics I can do a lot better. Esco optics is willing to make me some...

I first learned about optical trapping on this forum nearly a decade ago. At the time, I couldn't comprehend the science behind it, but I could easily do the experiment with a 200mW red laser. I decided to explore the idea again and make a video about it! I say in the vid that you'll need a red...

I keep a list of saved searches on eBay for various laser things...always hoping to get a deal on a one off part. In particular, I've been looking for a 375nm diode for at least 5 years now, and the cheapest I've seen them go is for around $900 (plus some 375nm coherent cubes that I missed for...

Decided to log back in and turns out I registered my account 10 years ago today! Can't believe it has been so long since I've joined. I figured I'd post some of my LPF milestones for y'all to enjoy. Avery, I'll take my solid gold LPF edition 495nm laser pointer that gets sent out to all the 10...

FS: 520nm Build in Stainless Steel Side Clicky Host, also bulk "A140" 445nm diodes Up for sale is a neat build that I finished this summer. I'm using a microboost drive with an Osram PLP520-B1 diode, and the build takes a single 18650 battery (not included). This is a slick build, and was...

Anyone ever mess with this diode before?? Datasheet These have popped up on eBay and I picked one up a while ago. I haven't done anything with mine yet, but I may fire it up soon if I get the time. They are cheap at least! Sharp 638nm 180mW Orange Red Laser Diode LD Single Mode | eBay I fear...

Years ago I got a lucky deal and picked up four Nichia "aqua" laser diodes rated at 20mW and around 476nm emission. These diodes were found to be really interesting, because when they are driven hard they emit a second 480nm line that is stronger than the 476nm line, and a diffraction grating...

Up for sale is my 3W C-mount red labby with 5W FAC diode! I am broke now and reeeaaally need the cash... :D The laser diode is driven by a PLD5000 laser diode driver (these alone run ~$100) and is currently set at 4A, which gives 2.9W in the current setup. This laser diode can safely take more...

Hey everybody! It must have been years since the last time I posted a build thread, but now I finally I have something interesting enough to post. :D Over the past few years I have kept an eye on the forums and eBay for cheap lasers that are either broken or old, and slowly I have accumulated...

Over the course of a year or so I've accumulated 4 broken C@$!0 projectors and have subsequently pulled 4 diode banks from them. In this video my buddy and I fire up one and burn the $hit out of stuff sitting around. :D The plan is to put all 4 on a laser gun for nearly 200W (before optics) of...

About a year ago, my quest for one of the fabled 5W C-mount 650nm diodes ended when Jmillerdoc kindly let me buy his. I bought a PLD5000 driver and set the current to a little over 4A, and dropped the diode into one of those common c-mount casings on eBay. I get a huge beam, but it is powerful...

Update 5 28: added a couple things...much more to be added soon The time has come for me to sell off most of my laser stuff. No, I'm not leaving the hobby, quite the opposite actually. I'm likely going to be moving across the country come August (going to grad school to get my PhD in optics :D...

Hey everybody! I am currently in the process of trying to build a solid state laser that is pumped by a charge of flash powder. Usually, people just use flashlamps to pump ruby and such, but if I can get a flash powder setup working, it would be cheap and scalable for LARGE chunks of laser...

Hey everybody! It's time for me to start selling off most of my stuff...I've accumulated too much stuff and I need cash for a couple crazy projects I'd like to attempt. So...first off is the diode bank off of my "laser shotgun". This bank has treated me well, and has not had much use. I ran each...

Hey everybody! Recently I spec'd out a bunch of diodes for a project in the lab I work in, and I felt like you guys might find it interesting! Two out of the 6 BDR diodes I tested were over 415nm...crazy! Results were taken on a recently calibrated Ocean Optics High Resolution spectrometer...
