That would be the kit right there. I picked up a pair of energizer CR2's from bestbuy, (I would have gotten the rechargeables but I was pretty excited for it)

I recently ordered a laser kit from odicforce with the LPC-815 diode. I assembled everything and when I turn it on I get a very bright flash of red for a fraction of a second then the output goes very dim (like I can only see it in the dark). It does this each time I turn it on. I'm not sure...

Combining lasers is easy. But how do you intend to deal with the phase problem? LASER OPTICS: Sixteen laser beams combined with 88% efficiency - Laser Focus World Now I'll give you one better. Mind you this is a PhD level topic. Combine all the lasers at one point. But pulse them in such a way...

It's all about the journey not the destination. Its better to feed my hobby when I have good reasons to do so. While I might not get it to work, I can def try. I have some more lucrative reasons for playing with lasers then most. So even if I fail I gain knowledge and experience.

A CO2 laser operates at 10.6 um 10.6um = 10600 nm :oops: I missed a zero. But It also means a YAG laser would be much better suited for marking aluminum @ 1064 nm :gj: A little more reading tells me a 5w Q-switched YAG laser can do it. Now to learn about Q-switching :D

Dont mind trolls. The machinery handbook tells me I need between 5-10W on a CO2 laser, so your approximation is spot on. I'm surprised no one's tried anything like this before. Aluminum shows adsorption at 1400 nm that's not too far from CO2 wavelength. I figured an GaAs/AlGaAs diode would...

How much power is needed to write on metal with a laser? Also whats an ideal wavelength for it? I plan to affix a high power laser to a plotter to get a laser marking machine. I would like to know if this is even feasible.

Agreed, link plz :wave:

Pm sent, lets see what happens

Re: FS: New PHR-803T sleds as low as $5.85 I will take two of them, PM me with your paypal info.

I like the notion of gravity just being a thermodynamic construct, and think it to be feasible definitely worth further examination. @Ash: of course there are some “experts” who refuse to even give credence to the new theory, think about it. If you spent your life looking for the higgs boson...

No bright flash either time. I know its the driver.

I tried it with the 5v lead from a power supply. 12A capable. Next time around I'll be using a current regulated power supply (actual plug in power supply), and eliminating all possible problems one at a time.

Furthermore can someone explain to me how a laser diodes actually "burns" out. This diode still looks just fine @20 and 400x.

Second attempt, exactly the same as the first. I done, I give up on lasers. Right now I'm banking on it being the driver, but do I really want to start all over from scratch. Hell I'm not even going to buy a prebuilt one, this must be a sign to not mess with such things. This is a new diode...

I did not think to discharge the cap after running it with the LED, its such a small cap how much power could it possibly store (apparently too much). Also I've not shorted the pins for any reason. So it could have been ESD. Strangely enough I've never had anything die due to static, maybe I've...

First image is living proof that an LED can take 300+ mA, although it starts to dim, and the camera flash is way brighter. Then a picture of the layout. Its a battery pack -> the driver -> its leads -> alligator clips + to red, - to the multimeter, multimeter to - of the driver. the driver...

Ok its toast, I'm just disappointed I couldn't even get one second of use out of it. Are DOA's common with this hobby? If say I dropped the loaded aixiz housing on my desk when unpacking it, could that have killed the diode? Can anyone recommend a replacement diode? Ideally something in the...

The aixiz module did come with a lens and spring, I used both. Whats the purpose of the spring? I could focus the light into a very fine point, with a line through it. How can I get the aixiz lens to collimate? Do I just screw the lens all the way down. Just to recap this diode is trash...

My first laser experiment was a failure. I purchased a diode from Hightechdealz press fit into an axis housing. Thinking the easiest way to get started with burning laser pointers was to have all the new things pre done for me so all I would have to do was build the driver and solder things...
