    PBS cube, or diode anomaly?? ML501P73

    I tried passing a 500mW mistu. diode through a PBS cube that was bought for 445nm. Odd thing is, when I rotate the diode, within a full turn, the power does not drop and the the beam goes straight through. I have never seen this and cannot find any info on it. Theres a 10% loss through the cube...

    Scorpion King 7.3W of beam expanded insanity!

    Been a while since posting here. Felt my latest laser was worthy of sharing with such a large group of enthusiasts. This laser was a custom order for a gent who is already using a WL Arctic to kill off some nasty little critters at his ranch. He approached me for what finally developed into a...

    Quick simple high transmission lens with an old PHR sled / Tutorial video included

    In my recent ventures to make a high transmission beam expander for 445, I ended up testing many different lens configurations. While on this path, I revisited the PHR, just to try something. To my surprise, the results were not bad at all, my only issue was that the lenses in the PHR sled are...

    DIY Green He/Ne Build. Mellow Yellow DPSS Hybrid

    So once again I got an idea.. Looking at an old He/Ne tube, more specifically, the 100% reflective mirror at the rear. What if I tried centering a 532nm module through the bore of the He/Ne? First thing to consider was loss.. Not a big deal, and to mix with a 1mW 632.8nm, would only take a few...

    Low cost thermal adhesive.. DIY Tutorial

    Probably the simplest thing to DIY that can save you some money.. Depending on the application, those small syringes of thermal epoxy can run out fast.. I have tried this personally, and was pleased with the results. Parts you need: -Fine mesh aluminum powder, not the pyro type.. It can be...

    Not crazy enough to try this one...

    I had previously tried making a beam expander for my showwx pico projector and was successful. I was able to shrink the picture and throw a further distance. So while thinking of a setup for this, I got to thinking.. I wonder if anybody else was playing around with similar ideas.. Well >...

    Diode Repair & Services / Internal Ground Re-Routing / LPC, LCC, SMOC, PHR 805's

    Since I joined the forum in 2007, one thing has plagued the red laser build. This not only applies to the handheld, but also the labby.. -Neg grounds Now many of us like red, and when we build one, are subject to limitations, mainly driver variety. Many of the drivers, we use will not work with...

    Beefy diodes on ebay...

    Came across a seller on ebay who has some nice diodes for sale. I have never seen a 15W c-mount but he has some! Check sellers other items. The prices seem a bit high, but he also has the datasheets for these. Worth a look into for DPSS work. eBay - New & used electronics, cars, apparel...

    DIY 473nm / FRANKEN-TEK B&W Transplant To Handheld With TEC

    Firstly, this project has been on my mind since acquiring my first 473nm labby made by B&W / CNI. I decided to gut a working labby which I had previously re-aligned. To minimize the guess work I wanted the best crystal set I had out of the surplus lot purchased. I machined the head taking extra...

    Name change JLSE aka wannaburn

    To my fellow LPFers, after some thought, I have requested my name change from wannaburn to JLSE. I've been a regular member since 2007. Back then, this was the first forum I had ever joined, and even today, the only one which I frequent. Back then, I was still learning and amazed that burning...

    Sold 1.2W 3-Mode Leadlight Pen

    I only made one of these, and will not be making another. The side clicky can be hazardous, even though I attempted to make it difficult to press. This laser is 3 mode with memory and can be used with 2x 1.5v AAA alkalines, 1x 1.5v alkaline for super low power of 50mW or so, or a single 3.6v...

    SOLDERING WITH LIGHT / 1.55W 445nm L.A.S.E.R

    A while back I melted some solder with a class 4 405nm, and have also tried it with a high power 445nm. Today I decided to try this again, but with the idea of actually soldering with one. The results can be seen in the below video. While it is nothing new, its an interesting idea which can be...

    Copper plating AIXIZ modules *GRAPHS ADDED*

    Looking for some input on this idea... I have tried this and it works, but is the idea of copper plating an AIXIZ module beneficial? Two things come to mind... 1 it makes for a tighter fit for the LD by adding a thin layer of copper, and 2, my thoughts are that the copper will assist in...

    *SOLD* 2.8W Dual Diode Monster 445 In Custom Host

    Made another dual diode 445. This one uses the aixiz 3 element glass lenses which takes away a bit of power, but also improves the beam over a G1 without correction. The head is comprised of 4 pieces, at the heart 2x A-140 LD's set in a 'knife-edging' array config. Batteries are 2x 18350 and...
