I think it's a bad translation, of which they named their company. Their logo doesn't help, either! Other lenses aren't squat.

Why hasn't there been talk about this diode other than a couple one post topics posted in the wrong forums (445nm, etc)? Considering that people are still making builds with the NUBM07 and this diode appears to supersede it, I'm surprised that this isn't available on DTR's site or even seems to...

I was looking for some reviews of (Polish) OPT Lasers 4 watt RGB module ( https://optlasers.com/rgb-modules/4w-mini-rgb-laser-module-with-75v-psu ) when I came across this unit in a search, which is apparently made by the other (China) OPT Lasers (seriously, is it that hard to find a unique...

Sometimes I swear Microsoft is deliberately trying to cause as many problems as they can get away with without it being provable that they are trying to cause as many problems as they can get away with. 14 system fonts? 2 control panels with settings for common elements divided between both...

Just some pics of a M462 running at quarter power through some Nikon binoculars that had been put to work as a beam expander and a picture of the very super extra high tech setup.

.... that can be delivered in femtosecond pulses which can carve a matchhead without igniting it. Another Ebay stumble that I thought was wayyyy too cool to not be posted here. According to the manufacturer "They vaporize virtually every material so quickly that heat influence cannot be...

Junktronics has the complete projector assemblies from which those high power multimode 405nm diode modules recently discussed on LPF have been sourced. The assembly has 20 modules+optics. It is mentioned that the output places the modules' outputs side by side in a line but I'm optimistic...

It's a product introduction for laser diodes and would be really useful for the beginner and well-versed alike to visually understand a variety of aspects about lasers in general, laser diode assembly/manufacture process and a bunch of other crap as well. For some reason, the little dudes...

When I was reading the datasheet for the Sharp GH04850B2G I came across this declaration in the notes at the bottom of the document- At this point it was pretty much accepted that decanning InAlGan diodes resulted in a quick death but this is the first confirmation that I have seen from a...

Just finished this today after getting the diode at least 2 months ago, then waiting for optics for several weeks to be shipped from Poland then revising the design several times as soon as I would sit down to build it. Lately I've been used to the divergence of the M462 and NDB7675 and though...

Just wanted to share my experience and some pics of a large Epson LCD video projector's zoom/focus assembly working as an excellent beam expander. An added benefit is that you do not need a collimating lens in front of the diode with this setup, the diode's output goes directly in to the...

Just thought I'd share this PL520 build I did a few months back to add something to the sound of tumble weeds rolling through the lands of LPF builds lately :) I wanted switchable output with the lowest output having some degree of eye safety (keeping in mind something should never actually be...

Does anyone have any information on these diodes? I was ordering a NDB7675 at DTR's place when I saw these new diodes he has put up https://sites.google.com/site/dtrlpf/home/diodes/n450-4-5w-450nm-laser-diode https://sites.google.com/site/dtrlpf/home/diodes/n520-520nm-laser-diodes but other...

NOTE- This is pic heavy. Please forgive me if the format comes out incorrectly, my intent is to have the pictures grouped in thumbnails so your screen doesn't get bombarded with pages of slowly loading partial images, only for them to finally load and then figure out that you really didn't need...
