    SOLD 1w 520nm handheld $400

    Today I'm selling my ~1 watt 520nm build for a decent chunk of money. I had this laser for a month and I need to sell it for savings funds. Please note that my laser power meter is about 15% off on reading the true power of any visible laser. For example if the meter reads 850mw the lasers...

    de-windowed NDG700

    So, earlier today, I started to play around with my "Big Grass Hopper" build, which uses the NDG700, and the window of the diode suddenly got dirty for no reason. Well, I thought it was dirty, and i wish i had a picture of it. So i did my normal cleaning procedure: I grabbed a couple of cotton...

    2W+ 445nm from Photonz

    Recently I did a trade with Photonz for his 2.3W 445nm Build for my 520nm Build. This laser is in a survival laser stainless steel host, using the 445nm 9mm diode running at 2.2-2.4-amps. The heat sink is copper. The lens is a g-2 glass lens for maximum power! Laser power readings: Photonz...

    55mW 532nm Viper Series

    Just got a nice toy from Dragon Lasers. This laser is rated for 55mW, but since it is a cni module laser, the power is slightly over-spec as usual. I love the gold plating on the metal parts of the laser! Good job DL! I was going to buy a more powerful pen but they were out of stock, so the 55mW...

    Bank error got me a free laser?

    So recently I ordered a 55mw viper green laser from dragon lasers for a total of $127 including shipping. The first time I tried to place the order the bank declined it and wanted verification, so I did and then reordered. It then appeared that dragon lasers gave me $127 before taking out $127...

    Cheap and reliable host from member?

    I have a 9mm 462nm diode in a module and I want a better host than a c6. Because those small heatsinks won't do me any good, my current laser heats up too fast and i want a better host with a better heat sink. My paypal is broken and I'm willing to pay a good amount of money through bitcoin. The...

    120mw 635nm brass laser pointer

    I took some scrap parts for my new 635nm laser pointer. This laser uses the opnext 120mw 635nm diode and a flexdrive to support a little under 3 volts. The batteries used are two radioshack rechargeable triple a's. I'm quite amazed with the power output with two small batteries and a g-2 lens...

    Back for sale! 1.7 watt 467-470nm Handheld

    Before you think this price is a little extreme, I don't blame you at all, considering that this laser cost me over $380 to build, I'm starting the price high and I'm willing to work my way down for the perfect deal. I want $460 for it. This laser uses the 9mm NDB7678 diode running at 2.2...

    Compatible Flashlight hosts?

    Does anybody know of flashlight hosts that are compatible for the standard survival lasers heat sink, other than the c6 and s4 host? I have been looking on amazon and I'm trying to find a normal flashlight that can be disassembled to fit a laser heat sink.

    462nm NDB7675 Handheld

    Finally, I got my hands on this rare-ish Blue laser diode. This is the Nichia NDB7675 462nm Laser diode at about 1.5-1.9 watts(not sure, still don't have a lpm) Once I received the diode in the mail I immediately fired it up at about .15 amps and I already could tell this blue is much brighter...

    200mW+ 520nm Handheld OSRAM PLP520-B1

    I'm happy to share the newest member to the laser family. A week ago I talked to DTR about the Osram PLP520-B1, though of course you know where the 200mw will be coming from, and I got my hands on Osram's newest laser diode. Here what it boils down to: This diode is driven at 550mA so it's...
