Thank you so much... I will do this, and it is nice to support a fellow enthusiast..... :)

I build light shows, and can get bulk diodes cheap, I really like the no press lab modules, especially for higher powers. But for 80mw and below, a 12mm copper ring module is just fine, and a lot cheaper..

Anyone have a faster way to press diodes into modules?? If I had a CNC I'd just make a jig. Using a socket and pliers works, but I'd like a fast way to mass install diodes. Thanks..

"Harvested" a few of these polygon mirrors over the years too... I never threw away a machine without tearing it down first.

I was a copier technitian for Konica and Minolta for 20 years. Also Cannon factory trained. Over the decades I have collected front surface mirrors, lenses, solid state relays, solenoids, magnetic clutches, I even powered a HeNe with a transfer corona power pack for a long time. :) I still...

Ok, so recently I scored 5 diodes, all identical 505nm (harvested, so I don't know the manufacture) , they were all in 12mm hosts and all have identical drivers. all diodes are operating at 5.5 volts 90-95Ma draw each. but one diode lases very bluish green. the other 4 diodes lase identical...

Sweet beams. I like the creativity with the setup. Great use of common items mixed with not so common. Since you said you love mirrors, never pass up a junk big TV from the 90's...... they have a front surface mirror inside that's like a yard square.

I could (and do) spend a fair bit of money at Techhood ... anyone else notice a price increase recently?? I have noticed watched (buy it now) items jump up by a couple dollars in the last couple days..

Visit your own profile, and poke around with the tabs, everything is there and WELCOME...... Looks like the safety thing got covered already. Enjoy your time here,.

My recommendation would be use a digital ohm meter to sort out polarity, (Of course I assume you knew that) and fire it up with minimal current and slowly jack it up. (again simple common sense) Can't wait to see how things work out....

The diode has a ball lens, intended for fiber coupling. hence the poor divergence factor. I avoid diodes with built in ball lenses.

Hopefully exchanging ideas we get can spark creativity in others. How many of you out there have torn apart an RC car to get the servo systems out? used a CPU heat sink to cool a laser? used a cell phone charger to power a laser? set your wife's cut crystal on a record player and shined a...

I found that liquid cooling for CPU use is perfect size, and within a reasonable budget. small radiators with muffin fans. An aluminum block drilled for water flow (thermal exchange unit) could be easily fabricated with just a drill press. Good luck. I can't wait to see how yours turns out.

They are theater projector components. New cinema projectors are using diode pumped DLP technology (My 65" TV is a Mitsubishi DLP) and the image is stunning. These modules make up the light engine in big screen projectors. They are very real.

Crude, but makes a nice cone. I fabricated it entirely from junk. the aluminum plate was a heat sink from a junk power supply, the "mount" is a magnet from a hard drive (super powerful) the motor from a toy. The magnet allows me to move the motor around for alignment, and it's super strength...

Yup... It's in a "Lab host" with a power supply. I think I would investigate the diode used before pushing this. I find it odd that the laser is marketed as 100mw, when the ONLY Sharp diode of 505nm that I can find anywhere on the web is 35 mw. so either the diode is already pushed beyond spec...

Thanks.. Next two lasers are going to be the 520 and a 638, This time I am assembling the host and heat sinking myself, Serious units of these wavelengths are expensive, the diodes are a bit cheaper and I want to hone my optics assembly and fabrication skills. Been doing the electronics end of...

I promise not to explode any brains with such things as "are photons a particle, or an EM wave"? or "How can a particle have charge and spin but no mass"? :P ....... Watch the video... They use lasers to demonstrate how we detected gravitational waves...

So what if I have to mount it to a peltier junction or build a liquid cooling system, so what if I have to mount it inside an old car amp chassis with massive aluminum fins, 10 watts of the most visible wavelength would mean being able to write text in clouds or in the smoke of fireworks. Right...
