    PLPM4L 656

    I measured a center wavelength of 656.3nm when ran for a quick burst at 1.5A. It's crazy how much red light this thing produces! I'm not used to so much 650nm+ light. :D Power tests will have to wait for the time being. Even though the beam is messy and divergent, the novelty of so much red...

    PLPM4L 656

    Beam at 11ft gives a divergence of very roughly 25mRad. Beams are not aligned with each other well. Both the beam alignment and divergence are worse than the nichia blue LDAs

    PLPM4L 656

    I bought some of the arrays off of AquaticHarpy and I'm finally getting around to running some tests. These are indeed legit red laser diode arrays. It's pretty wild that AquaticHarpy was able to buy these so cheaply from an eBay auction as I haven't yet been able to find anything like this...

    Ultraviolet Lasers?

    His GITD projectors are INCREDIBLE. It was a treat seeing one in person at least year's SELEM.

    Ultraviolet Lasers?

    yeah it was an eBay find

    Ultraviolet Lasers?

    it was $150

    Ultraviolet Lasers?

    My best skill in this hobby is eBay. :D for that 375nm pen build I bought an "as-is" Melles Griot laser head that luckily had a good laser diode inside.

    Ultraviolet Lasers?

    Why do you need a UV laser to shine that far? It'd be easier and cheaper with one of these https://www.ebay.com/itm/DC-3v-6v-to-400kV-400000V-Boost-Step-up-Power-Module-High-voltage-Generator-new/191879578507?epid=0&hash=item2cacea038b:g:C10AAOSwJ8hcdygO (it's a project I'd like to try soon)...

    Feeler for Jetlasers Group buy #11 NOW ONGOING!! post your choices and comments TYVM

    Thanks for the info! In that case put me down for a 800mW 532nm PL-E Mini, but if they only go to 600mW I'll settle for that! Yeah I realize the brightness difference is pretty negligible, but 800mW of 532nm in a host that size would be a bit of a feat in itself so I can't help but want it. :)...

    Is the 532nm PL-E Mini offered up to 800mW in this group buy? On the website it only goes to 600mW.

    Is there still time to jump in on this GB? I'd probably pick out a laser or two if so.

    NUBM31T 95W 455nm

    Finally got around to messing with mine! I'm running all 4 strings of diodes in parallel at 3.2A per string. Beams aren't perfectly aligned but look better than I was expecting. The raw output power of visible light in a handheld laser is INSANE! I think the beams point slightly inward or at...

    New! Sharp Diodes 1W 520nm & 5W 455nm & +2W 638nm

    yeah I'm more interested in those FAC corrected diodes!! For the record I've ordered from the eβay seller linked to in the OP (sabzh21) multiple times and my transactions have went well.

    Styro's New 1,000,000 W Laser

    Most projects get parted out for use in other projects, but this one is so much fun I keep it ready to go at my shop. :D

    Styro's New 1,000,000 W Laser

    On a somewhat related note, check out these cheaper tattoo removal units on e bay: https://www.ebay.com/itm/Portable-Home-Picosecond-Laser-Tattoo-Removal-Pen-For-Mole-Dark-Spot-Acne-Scar/142772125642?hash=item213de1bfca:m:m3k-hEKE6YvbkqVYF5vXHXA I own one, and it's just a >1W 445nm laser with...
