    And the insides? It's what's inside that counts. And why the choice of the Intel board? I'm a workstation boy myself, my rigs tend to be much more restrained. Allendale: Network file server Really, nothing fancy. E4600 and a pair of 40GB IDE drives. Seriously, though, I can't quite afford...

    PGL-III-C <80mW 473 nm

    Re: PGL-III-C 40 mW(Should be >80 mW) 473 nm Oh man, that was painful to read. Since when did 'let's-shit-on-the-font-and-size-buttons' approach cut it? In any case, if it hasn't been brought to your attention already, CNI uses blanket labelling for their stickers. Often it's by wavelength...

    OEM lasers in 26.5mm modules?

    Yeah, the 'OEM 26.5mm' format is called a P60 drop-in. There's a metric shittonne (I'm not lying about the 'metric' part), and they're all different. I have a handful of L2s and a C1, all from Ultrafire. All take a P60 drop-in, and in each of them, the drop-in sits differently. There's a fair...

    Pump wavelengths for KTP?

    If I also remember correctly KTP will not double below ~500nm without a drastic loss in efficiency due to the inability of it to be phase-matched below 500nm or so. That would be the reason why it isn't used with 473 and 457nm systems- if it could, then, they would have. Besides, as Steve...

    3W 445 + 1W 532=white WHY?

    It may not actually be the eye overloading, there is another plausible explanation. I've observed it with the Arctic and a 250mW greenie before, it's similar, instead of blending to produce a turquoise/cyan, the blend appears to be a very off-white colour. It can't be overloading of the...

    Quick Q: Non electrically-conducting thermal-conductor?

    Arctic Silver and Arctic Alumina adhesives (the epoxy type that comes in the two tubes) is not conductive, and works the same way as your standard two-part epoxy. Mix, set and forget. It also works significantly (often ten or hundredfold) than those crappy thermal 'pads'. These pads often have...

    Game: Guess the mystery object !

    Yep, that was the rotor from a siren. The rotor itself is actually tiny, the Thunderbolt was a blower-forced siren.

    Right, my turn. Reposted :P Clues: 1. Chop Chop. 2. Thunderbolt.

    Game: Guess the mystery object !

    Seeing as I'm going to miss the time zone anyway, and because HIMNL9 probably won't be back in a while, I'll post mine up. Good luck, have fun. ;)

    Game: Guess the mystery object !

    Time zone differences, sorry. I'll wait for this round to finish then I'll do mine.

    Game: Guess the mystery object !

    So it's a burner for a gas lamp? Those are mantles. They attach to a burner and they glow to give off light.

    1 Mega Watt Pulse Laser Gun in High Speed

    A BDR-S06J is also similar to a GGW-H20L in terms of wavelength and construction. Are they the same? No. Remember, Nd:YAG rods will have differences between them. These differences include any impurities in the YAG host, and the concentration of Nd ion doping. Every rod will be different...

    1 Mega Watt Pulse Laser Gun in High Speed

    He was referring to the YAG rod used in the laser (the SSY-1 head), not any YAG rod. YAG rods scale up very high, much higher than 1MW.

    1 Mega Watt Pulse Laser Gun in High Speed

    Do not forget not all of the input energy is converted to output power. It takes 15 Joules to get 200 millijoules out. 15 joules in the space of 100ns (the pulse duration of the flashlamp) is 10000000 watts. (10MW) 200 millijoules in the space of 100 nanoseconds is only 200000 watts. (200kW)...

    1 Mega Watt Pulse Laser Gun in High Speed

    Fights? We're just trying to point out some of the stuff you are obliged to disclose yet failed to do so. Did you read anything that I wrote? You obviously have no idea as to the power and danger of the device you've built, and now you're planning to sell more. There's no safety features on...

    1 Mega Watt Pulse Laser Gun in High Speed

    Your attitude here is absolutely disgusting, even for a new member. You barge into a thread on a topic which you obviously don't know anything about, and start bashing a veteran who actually knows what they're talking about. First of all, you quite obviously don't know enough about wavelength...

    Laser beam of 30km?

    A beam expander can help reduce this divergence; Laserglow markets their Hercules series of green portables for this purpose. It's in their April newsletter, on this page: Laserglow Technologies - Handheld Lasers, Alignment Lasers and Lab / OEM Lasers Even then, over 30km, the beam will have...

    1W 473nm for $253.56

    Put it this way- yes, they have a very high TDP, and like you said, up to 12W of heat energy to be dissipated. Now, in those hosts, the main priority is getting the heat out of the LED, and keeping it below it's operating temperature ceiling, which, for the P7, happens to be 85C. Now, as long...

    Anyone ever shine their 1W+ 445 on one of these?

    Unless there's a remote 'detonation' system in place, they won't pop on their own accord without external force or heat being applied to them. They work by the red glass envelope bursting, releasing the water behind them. Unless it has electronic triggering, one of the heads triggering won't...

    Laser goggle fail

    What you are seeing is entirely normal. The sudden, bright orange glow isn't coherent laser emission, instead, it's fluorescence of the object that's being lased (in this case, the post-it note). None of the green would make it through- what you are seeing is emission in the yellow, which isn't...
