With my birthday coming up my wife said I should treat myself to a new laser (LOVE that woman!). I thought about a yellow pointer but I already have yellow. I saw that the Valkyrie 488 was on sale (and 250mW) and I didn't have that wavelength yet so..... The package: The laser came well...

So, I have around 150 100watt LEDs left over from my days building lights for.....indoor gardening enthusiasts. I know it would be illegal to position an array of 80 or so of these along the bottom edge of the rear window of my car wired to a momentary switch to deter tailgaters @ night...

Perhaps I wasn't paying attention, but what happened to DTR's laser shop? I just went there and it's all dead links :-(

I hadn't realized this technology had become this advanced. These folks are proposing using millimeter wave masers (gyrotrons) in the many megawatts class to drill 10s of miles deep to harvest geothermal heat for power generation. A quick trip to wikipedia to refresh myself on what exactly a...

Let me know what you think about this:

Looking around on alibaba and saw this. Smells like BS but....... https://www.alibaba.com/product-detail/575nm-laser-Diode-modules-574nm-laser_1600236664933.html?spm=a2700.galleryofferlist.normal_offer.d_title.1d3b533dJxRD1L

Trying to make up my mind about something and I thought I'd ask the opinion of the forum. Here's the situation: Linkedin keeps sending me a job recommendation for an engineering position at a rapidly growing laser company that happens to be within driving distance of my home. They've been...

Well darn. My EDC, (PLP520-B1), has died a thermal death. My wife and I were trying to figure out where the smell of burning paper was coming from on Sunday. I now understand it was from my jacket. My poor laser got stuck on (again) and I had the good (NiZn) batteries in it. Darn near lit...

Found this in my laserist facebook feed. Don't know if this link will work: https://www.facebook.com/photo.php?fbid=2438121779597324&set=a.204037943005730&type=3&eid=ARA3qmXtPuaLGJeTyXlmuCUoe2uaMPf_xKjUcbCxqDLv-esfXHEdI_rz96lXCDtrU2cU-43bdorZ5vL5

But can it light a match......... https://arstechnica.com/science/2019/09/trampoline-mirror-may-push-laser-pulse-through-fabric-of-the-universe/

Anybody seen the "Night Hero" binoculars? ( https://www.target.com/p/as-seen-on-tv-atomic-night-hero-binoculars/-/A-53808231 ) I saw these in wally world last night while I was waiting in line at the register and saw the words "night vision laser" on the box so I checked it out wondering...

https://www.cnn.com/2018/06/20/health/laser-pointer-eye-hole-study/index.html Why do kids seem to feel the need to stare into a laser pointer? And no one tell the doctor they interviewed for the story that there are now 7+ watt handhelds available, OK? Poor kid.

Well, that was.... interesting. I blew a disk in my neck and I've been off-line for a couple months. It took my right arm away for a few scary weeks but fortunately, this is a common enough problem that 'they' have gotten very good at repairing it. Outpatient surgical clinic right between an...

Finally making a little progress on the TEC cooled '07 I've been wanting to put together. The host will be an old bar code scanner gun. @ 12volts in, with the TEC wired in series with the driver input, diode current is @ 3 amps, output power is about 3.5 watts, and the diode is sitting at 12...

What happened to candlepowerforums? I tried to go there tonight and got 404'd. What's up?

Well this is interesting. When the system is refined maybe we can compete with the musical tesla coil guys: https://arstechnica.com/tech-policy/2018/03/non-lethal-weapon-dod-seeks-to-use-lasers-to-create-shouting-will-o-the-wisp/

So apparently Fresno is not the place to play 'shine the laser at the helicopter' games....But what pilots have suffered permanent disability due to a laser strike as stated toward the end of the article...
