I really wanted to make some lasers that take into account gaps that I have experienced myself with laser builds. so I set out to build some real quality 3W 9mm 445s using sinner's nice copper head hosts. I put considerable time into them, hand machining copper heat sinks for the build. I put...

I am offering 3 lasers from my latest build. First I'll get to the bottom line. If you want more details check at the end of the post. There are 3 of these, labeled A, B and C. Each has built the same way and you can see from the pictures the nature of the build (details at the end of the...

I am trying to get a PL450B single mode build happening. I am using a Microboost. did the usual things: set my dummy load to 8 diodes (~6V drop), connected the driver to the load and battery (18650). measured the current on the load (1ohm) and set it to 350mA. of course solder blobbed the driver...

Just something I've been working on...

Here is something a little unusual. This is a PL520 520nm green laser diode pressed into a copper module with an acrylic lens for $50. This is a DTR diode module, that he sells for $79. so why only $50 - there is a problem, jim. Below are beam shots of the raw beam out of the diode. The other...

There was a group buy with CNI some time ago. A member bought a 589nm 80mW from the group buy and ended up selling it to me shortly afterwards. The laser had some issues, a beam coming out on an angle, and the beam profile was smeared. I sent it back to CNI for repair. they replaced it and here...

I thought this might be of use to some of you. seems like a useful device if you really want to accurately set current. EEVblog uCurrent - Precision nA Current Measurement Assistant [v3] ID: 882 - $59.95 : Adafruit Industries, Unique & fun DIY electronics and kits I follow his channel on...

Originally this thread was about Wicked Lasers possibly using content from someone else, but daguin and DJNY set the record straight pointing out that Warnlasers and Wicked Lasers are associated. so i have edited this post and subject accordingly.... I was googling yellow lasers to remind...

I am looking for the above. PM me with what you have and asking price as a start. thanks

I have a Firedragon III and it stopped working. I heard a rattle inside. I took the lenses out to find the KPT and retaining brass wedge had come free. My laser is like this one: http://laserpointerforums.com/f52/dinodirect-firedragon-iii-300-mw-updated-59757.html I have the laser and OC lens...

I got myself a 3D Printer (printrbot) last year. since then I have gotten competent with CAD such that if I need anything, I can usually design it up fairly quickly and print. A couple things came to mind: first, I have a multi-line argon that I like to attach a diffraction grating to. i have a...

I just got the latest release of LumenOS for the Kenometer Pro. I have to say its excellent! The user interface and screen layout is much cleaner and clearer than the original. Also, the noise reduction and smoothing functions are really good. Better to do this in software than hardware. My Pro...

Hi there! I am cleaning out my collection and have some nice lasers for sale. Some notes: first, you must be 18 years or older to purchase from me. second, if you are a new user with <40 posts we will need to PM a little more before I will agree to sell to you. I will not take any...

I've been getting a dialogue to re-submit a form (or not) when pages load especially on the buy/sell forum. when the dialogue come up it prevents any use of my browser. i am remiss to hit submit because i don't know what is causing it. eventually i have to try and close the window before the...

I will make this short: purchased a "500mw power certified" Firedragon as part of a LPF group buy. What I got was a laser that barely does 450mw and seems to operate in TEM01 (certainly not TEM00). warming up doesn't help. measurements on a calibrated Kenometer Pro. The return policy on their...

I purchased Escher's optical table, optics and mounts. I just got them yesterday and put these two little configurations together. Its tons of fun doing this kind of "light art". I am using a Meirlights 250mw 532nm an Ultra Lasers 180mw 473nm, both labby's. The divergence on the Ultra Lasers...

This is just a pre-review meaning there is not much here... yet. But this is an important bit. Cold start power vs host temperature on a freshly charged AW 18650 2.6Ah with an Kenometer Pro with Ophir sensor. This is not IR filtered. Using a Hoya R72 filter that passes about 90% deeper than...

My girlfriend doesn't understand my laser hobby. She thinks buying these lasers and shining them around, through optics and smoke is silly. What can I do?

I purchased this laser from wannaburn directly from a for sale ad he has on the forum. The promise of a laser that takes a single AAA sized battery and can output a watt of visible light energy was a far greater force than having $200 in my pocket. So I gave that to him and he gave me this...
