    Bright flash then dim

    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)

    Bright flash then dim

    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...

    Best way to combine Beams for Power?

    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...

    Laser Marking Metal

    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.

    Laser Marking Metal

    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

    Laser Marking Metal

    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...

    Laser Marking Metal

    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.

    A Scientist Takes On Gravity

    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...

    First Attempt (fail)

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

    First Attempt (fail)

    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.

    First Attempt (fail)

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

    First Attempt (fail)

    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...
