This is pretty simple guys. If you have ever removed the optics from a laser then shined the "flashlight beam" around you are 99% of the way there. If you have notice the sharp shadows it cast and made some shadows you are 99.99% of the way there. Do you have a can of "air duster"? Possibly...

Well after two years procrastinating/deciding if I was sure I went ahead with it. I have at least 6 years of GI Bill, but they have gone to 8 for Veterans after Dr. Montana offers 6 more years ON TOP of the GI Bill after it runs out under the Veterans Education Benefit. My local community...

Diamond Solid State MASER Detailed Technical Article in Nature My first thought was application in propellantless RF Cavity thrusters. Since they require very finely tuned microwaves to produce the thrust effect...

I'm looking for a 22A 4V driver. (2 26650s as power source) A small driver with the ability to use an external adjustable pot (as blackbuck M8) would be great. Any designs for such a driver would also be useful.

First a shout out to DTR and his 2W 470nm+ C6 20mm Overdrive Special for inspiring this build as well as the 20mm module assembly. Also kudos to Survival Laser and their fast shipping and helpful customer service. Also sorry for the low quality pics, I have yet to invest in a good...

Engineers Turn a Laser Beam into a Stream of Liquid Light usually passes straight through water and so can’t generate a stream of fluid, right? Not anymore.

I'm looking for a good simple build host for 12x30mm modules. Looking for something 14500, 16340, 10440 powered.

I want to upgrade the software (unlock code) to the 6 watt (Ag) version. I want to get the non-coated version of the sensor and any software needed to upgrade to the 20 Watt version. I would also like to learn more about the data logger and start using it. Yes, I have tried contacting...

New material absorbs 99.96% of light, Guinness World Record darkest substance. Would make a good wrap for gas tube lasers. Other ideas?

I contacted Opt Lasers about getting just that fantastic mini mount with mirrors. They said they would send me one for about $200 I'm basing this build idea on perceived brightness. Osram PL520B 520nm max pot set to 275ma for 120mw green Oclaro HL63193MG 638nm max pot set to 1.2a for 1050mw...

Nearest I can tell, is this Stirling Engine should be putting out about 6v and at least 0.03 ... amps. I think that would push an efficient diode/driver combo to about 10mW or so. It would show from the discovery of fire, thermal to mechanical, mechanical to electrical and electrical to...

Yep. Since everything is going so smooth with my Phaser build, and I plan to get one of Rick Trents 7w units I'm thinking of my next build. I have been playing with this idea a while. The new blue/blue Dichro works on such a narrow spectrum that binned/sorted NUBM44s can be combined. 2x...

I read a thread about combining two NUBM08 of slight variation using a blue/blue dichro. This got me thinking about trying the same with a pair of NUBM44s. 2 pairs of NUBM44s PBSed x 2 dichroed and you have up to 28-30 watts all on the NUMB44 beam profile. Add a beam expander and you could...

I want to build a Fabry–Pérot interferometer in order to study and understand the equipment and technology. Fabry–Pérot interferometer Wiki It is also an excuse to buy my first "Lab Laser". I intend to use this device to attempt to measure gravity. (proximity or even orientation to a large...

WOOO HOOO SUCCESS!!! I HAVE GOTTEN MY WAND PHASER APART WITHOUT DAMAGING IT!!! Alright I got it apart. The first step is to remove the "cooling fins" I used a pair of taped pliers to prevent marring and pulled firmly with just a little wiggle. Be careful to grip it about 2/3 back because the...

A - My soldering skills are basic, I've watched the "101" and searched (using the google bar) to see what advice I could find, I was left with (strip everything) or stuff specific to particular hosts. B - Of all the info I'm learning the drivers/boards/circuits are the most complicated. I...

CLEARANCE Sale Powerful 5mW 605nm Red Beam Laser Pointer Pen Light Toys Xmas | eBay I was thinking about adding it to my collection if it is indeed 605nm. I suspect it is a dyslexic 650nm...

So I've been browsing flea-bay searching flashlights by battery configuration and this is one I grabbed up. 3500 Lumen 3 Modes CREE XM T T6 LED Comapct Flashlight Lamp 14500 Battery JS | eBay I am pretty sure I can stuff a Oclaro 700mW 638 (HL63193MG) diode in it and run it at 1w. I am also...

'Star Wars' Laser Kills Mosquitoes Any ideas on building a economical version? Motion tracking, auto focus cam and a "Fire" or "Next target" mode. You know, sit on my laptop and wage war on the flying bugs.

Here is the diode in question. 808nm 10W High Power C Mount Laser Diode | eBay I was wondering what you guys think this diode might top out at. I'm considering PBS combining 2 then using a Dichro to add a visible light beam (probably from NUBM44).
