The NDG7H75E looks like any other generic 9mm diode with a small window and no case pin. At threshold it lases at 530nm and shifts up to 532nm when driven at 1.5A producing 1.3W with a G2. Cramming the maximum amount of heatsinking and a unique diode into the host were the main goals of this...

On todays episode of things that shouldn't be done but it looks pretty cool anyway, I've made a 1W green pen laser. The diode is a Sharp GH05C01B9G, I have several of these but this one doesn't wavelength shift as much as the others I have. Where others push up to 525-527nm @ 1W, this one...

I just saw Alex2893 has an Jet Lasers Dazzler for sale that uses a fiber coupled multimode diode and produces a round spot, effectively neutralizing the naturally bad divergence of the laser diode. It got the gears turning in my head and now I'm wondering if it's possible to this with the new...

With a bit of searching for a good looking side clicky 3X18650 host I found a flashlight I liked and quickly drew and printed a heatsink and cap as a proof of concept. After hitting up Lifetime17 for some machine work he sent me this beautiful piece. The solid copper heatsink is even...

After a month of waiting, the NDS7175 has finally arrived and it is glorious. Rated at 2W I'm only feeding it 1.3A and its producing 1.2W @ 489nm through a G8 lens. In terms of divergence its identical to a NUBM07 using a G-ball adapter and G8. This diode has a remarkably low max operating...

I'm joining the big boys now! My NUBM35 blaster was fun but now I've finally made it into the +100W handheld club. The laser won't win any beauty pageants but it was made with simplicity in mind. A 3/4" aluminum square tube was run along the top and bottom of the laser and make up the frame...

I'm trying to repair a DPSS green laser with a blown pump diode. The original diode had a FAC so I ordered a 3W 808nm C-mount diode with FAC from LaserLands. I don't know what power the original diode was but after measuring a drive current of 2.2A, a 3W diode seemed like a safe bet. The...

While messing around with my WL Spyders I noticed my older Arcitc has a different "100%" lens than my newer one. Compared side by side you'll notice the left one reflects the true white color of my ceiling light while the right one has a bluish AR coating hue to it. Doing some power tests I...

Probably a long shot but does anyone have a Wicked Lasers Spyder Inferno they would part with? I've got one of the older Kryptons (back when they were 532nm DPSS) a Lunar and an Arctic and I would like to complete the set with an Inferno. I know for true completion I would also need the 520nm...

Ever since I stumbled across Dr.Laser's old thread about his 577nm GLP he had built directly from CNI I've wanted one of my own, even with the eye watering price tag. I knew it likely wouldn't be possible to get a complete GLP through customs but a correctly sized module should have no problem...

Using an old Laser Glow Elecra as a host and a Dragon Lasers' 473nm module I've put together an LG Aquarius equivalent but in a black and gold host rather than a Blue and gold one. Having never purchased from Dragon Lasers before It did feel a little weird wire transferring $400 to China but...

I didn't think it would be too difficult to get this wavelength but thus far my attempt to get a 650nm laser diode has been unsuccessful. I have purchased what were sold as LPC-836 and LPC-840 "650nm" laser diodes but they have measured out at 660-661nm. https://www.ebay.com/itm/134123253933...

Having seen a couple people turn the laser arrays into portables I wanted one of my own. Though not quite ready for a massive NUBM36/37 I went for the smaller NUBM35. Even still i wasnt quite ready for how much heat the array produces and the run time is still quite short even with the what i...

I have a BDR-209 that is at 410nm but I've heard some people have gotten theirs up into the 415-418nm range. Has anyone spectro-ed one of the Sharp GH04W10A2GC diodes when its pushing out 2W? I might pick one up just to see. On a similar note I had some cheap 405s from ebay that sat in the...

A long time ago someone made custom stickers with wavelengths and output powers, I dont need anything that fancy. I'm just looking for any generic DANGER sticker that is suitable for a pen laser. I just completed these 4 little beauties but removed the original label as they were awful bright...

Laser colors have come a long way since I dropped off back in 2013. I've spent the last 2 months reading through years of posts and purchased a half dozen modules from DTR to fill out my laser spectrum. In my reading I came across the curious little 561nm from Lasence. I managed to acquire...

I just finished a little 2 axis laser etcher of sorts. It uses sleds from dvd drives and is controlled by an Arduino. I am by no means a good programmer so the code that controls it is more than likely horribily ineffecient, but i am happy that it works. So far ive made three different...

Here is my attempt a your basic beam expander. The whole thing consists of just two double concave lenses and a dichro. All three of these optics have been taken from an A140 projector. The laser is an Aixiz 50mW labby, with which i have removed the final lense from and in its placed...

Originally my SSY-1 was being powered by some disposable camera flash circuits and capacitors. While that does work i wanted to have something that takes a lot less time to charge. So i rebuilt it with a ZVS driver powering a rewound transformer for my main charger. Ionizing the lamp is...

Im a littlle late to the game, but i finally got my first 635nm. Its based off the 300mW diode and driven at 700mA from two AMC7135 regulators. The host comes from focalprice and was originally a green laser that had rather poor stability. At $16 i had no problem ripping it apart for the host...
