About 5 years ago, my daughter and I built a custom 3W 405nm DTR diode laser. It's a simple setup, with a copper heatsink/diode holder of around 100 grams. It's a simple 18650 flashlight conversion. I'm using it at work, and frankly, with the new diodes out, and me being so busy, I'd really...

Hi, all. I'm finally back, and I'm unloading my toys. Up for sale, today, is the world's first 520nm diode in Sinner's MS-SSW. This little beauty generates just over 100mW, runs on 2 X 26650 batteries with a total capacity of 8000mWh. You could literally run this lasers for 27 hours before the...

Hi, all! I know it's been a very long time since I've been around the forums. I went through some difficulties, challenges, and a change in jobs. I'm offering up for sale my Ophir 20C, along with the custom heatsinking I built for it, and the power supply, as well as the PS and DMM interface...

We should make this an ongoing thread with links to peer reviewed journals, multimedia, etc.. Anyway, on to today's find: How about a diamond, being suspended in a vacuum with a beautiful high-powered laser? I'm guessing a high-output 532nm. I'll link to an article or this experiment, if I...

My 520nm MS-SSW and 450nm Kryton Groove My 520nm MS-SSW and 638nm Kryton Groove

Hello, all. I'd like to make my apologies for not being active lately. I was able to participate often while I had a wonderful assistant, combined with a slow period at work. I had it made. I had my bench PSU, heatsinked Ophir, great DMM, diode test/punishment heatsink, tripods, clamps, orders...

What kind of sorcery is this?? Now, my boys can play with a 3W dot around the house! "I don't know where all those scorch marks came from, honey..."

So, I was picking up my daughter at the airport. I was in my little Toyota Solara, which has been a trusty used car we got from a friend. She's got ~168K miles on her. We've hardly had to do anything to it in the 2+ years we've had her. Well, the little Toyota, named Stella, suffered a fatal...

Don't get too terribly excited, just yet folks. But, here's some great news for all of us who have done some damage to our retinas. First successful transplant of retinas made from embryonic stem cells - FierceBiotech

Well folks, I am down to my last 2 Kryton Grooves that I will be offering for sale as full builds. I'll offer them in 9mm 445nm, and in single-mode and multi-mode diode builds. I will have Mrcrouse machine out the Krytons for press-fit modules, should someone want something in 3.8mm. The price...

I don't know who this guy is, but holy crap! :drool:

Why, with lasers, of course!

Not much. But, here ya go... From my single-mode collection: 638nm - To LPM in Kryton Groove 520nm - 115mW in MS-SSW 450nm - To LPM in Kryton Groove

So, I've been very busy at work in the last two weeks, with my assistant out due to a torn hamstring. Now, usually, I have the time to handle the sales and repair of the vacuums, and get plenty of time to work on lasers. Of course, as soon as my assistant is out, we suddenly get bum-rushed with...

Hi, all! It was time for me to upgrade my carrying case. My old one wasn't cutting it anymore. I don't have a lab at home (no space), and I don't trust leaving my expensive equipment around my shop (meth heads). So, I needed a case that was big enough for not only my lasers, but the more...

I don't know why I didn't think of doing this before! This is a little bit rough. I am thinking of reproducing it. I hope you enjoy it! From video description: Bucky Ball cube of 216 magnets, being lit up with four lasers. Proper eye protection was worn during production of video. Lasers are...

Well, I received word that my veteran status has been revoked. It's a very disappointing turn of events. I do understand the reasoning (to be fair and strict to the rules), but it still stings. So, for all the vets that were bothered that I was allowed to be a vet, you need not worry anymore...

Hi, all! I'm offering up for sale my NIB 5W Ophir 20C-A-1Y from Cclem on Fleabay. I'm only asking a pittance more than what I paid for it @ $240 plus shipping. If you're interested in extra heatsinking, let me know. We can work something out. SBA
