Technical specifications:
Material: Metal
Light color: Blue-violet
Power: 1000mW
Wave length: 405nm
Working voltage: 5V


Question : how to feed it by pulling the module 12x45 with a diode and minidriver and putting it inside of a flashlight ? are not yet practical of these procedures ,i only have battery 3.7 V Li-Ion battery 26650 - 5000mAh

How about a link to the 1W 405nm Laser Module
you are referring to...

Could we get a web link rather than a picture. Might help. :)

Looks like you want to put a square peg in a round hole! :crackup:

You have to be joking, trolling, or just don't know or use english well.

You need to pull the actual 12mm laser module out of the Al cube heat sink and go from there and put in a flashlight using a proper round heatsink/module that fits the flashlight host either premade or make one but of copper not PLA

You can see how to put together a functioning handheld basic laser here: http://d11fdyfhxcs9cr.cloudfront.net/templates//58770/myimages/Survival_Laser_BB_Parts_Bundle_Inst._Small_5-26-11.pdf

Many different models, wavelengths, and build assembly tutorial instructions are listed at bottom of this page if you scroll down to the list here: Survival Laser International Home

If you need diodes, drivers, good copper modules you can find and purchase them here
at LPF member DTR's business web site, along with other items that are useful--he also sells o ebay and amazon.com:

I'm wondering what diode is has. If it is a single mode, then the 1 watt claim is probably over-hyped. If it is a multimode, then you would lose all the great beam divergence that comes with the former. In any case, if you want to put this into a handheld pointer, it could be done cheaper and easier than to try to cannibalize this assembly.

Looks like it is this module.

The seller says Nichia diode but not which one but Nichia only makes multimode high output 405nm diodes 600Mw and 1200mW so....

@ Encap
Yeah, you are probably right. If they are using it for engraving, it would work for that purpose if close enough to the engraved object. I don't think it would be a particularly great diode for a pointer. The 12X or 16X would be better options as they both have a better profile. I'm assuming that the price from aliexpress doesn't include the driver. It would need to be modulated for engraving. :thanks:

In response to all of You...!

The laser module 1W as shown in the picture , it's totally removable at all from the form of dissipation ! the entire diode module is already equipped with a laser diode 1W and mini driver-welded , my question was : given that the protruding wires + and - , how can I feed it by placing the entire module diode inside a led flashlight (empty) with only one battery, 3.7 V L-Ion battery 5000Mha? given that the Working voltage to 5V ! I don't know if I was clear !

In my opinion this probably uses an over driven 16x laser diode. Look at the price!!! A 1200 mW 405 diode is a lot more expensive, and this goes for both the multi mode and single mode variety. One can look them up on the web and see the cost differential.

I've seen a lot of these 1 watt 405nm laser modules on ebay and have also thought about cannabilizing it for the dioide and optics, as doing some astronomy laser pointing and then swapping out for hand-engraving would make for a very versatile handheld.

Now granted, Violet is about the worst color pointer you could select for astronomy, as along with low preceived brightness, it'll annihilate the eyes dark adaption from "visual purple" our bodies generate to see in the dark....so while I'm aware of everything against it, a dark violet, or to be more precise, the emission nebula hydrogen plasma mixture of red & violet, is my favorite color and well, I make no apologies.

But less about my build ideas.

It would be great to get some kind of definitive word on if these modules use an over-driven diode or can sell quality diodes with high-duty cycles, at such a low price simply from buying in bulk.

I know this post is near 1 month old, but a violet laser with low divergence & in this whole number wattage range, is definitely something I'd also like to put together, perhaps combined with a red by using some kind of beam combiner. Dichroic mirrors?

So to the OP, 3DLaSeRBuiLDeR, I've seen your finished 1 watt ~450nm topic report-in, and was wondering how you've progressed in building your 405 violet?

It's more fun rolling your own.

If you order a BDR-209 16X blue ray diode with a boost driver and three element glass lens from DTR's website, it will cost you $71.00 and be ready to solder two wires and drop it into an appropriate host for a 700 to 800 mW laser already to go. I don't think you can do much better considering your limited experience building these lasers.

Has anyone ruled out a mis-labeled half-watt 405nm, or a regular 1W 445? This IS a random Chinese listing.

DTR stocks an impressive array of diodes however I'm pretty familiar with electronics and so would prefer to just buy the diode. Drivers I can do, diodes... not for a few decades yet.

Presently however I'm thinking about just combining the light from a ~ 5 watt blue 445nm diode together with a red diode, to produce the "violet" color, without actually using violet diodes.
