Hello DTR
I want to build my own laser.
However, I am not confident of full DIY
I understand fully DIY is
Take laser diode, insert in copper tubing, put lens in front, then solder driver to the diode and then take apart a flashlight.
However, your 77$ PL450B kit https://sites.google.com/site/dtrlpf/home/diodes/450nm-pl450-diodes seems interesting
With 200mA current what will the laser be? 600-700mW blue?

Once I get this module with driver attached, all I need to do is find a ultrafire,trustfire flashlight, take out the drop in module, and put this module with a heatsink around it?
For heatsink I am thinking of raiding an old motherboard and drilling home in aluminum

I was searching the forum for "Easy way out DIY" thread, but could not find any.

It would be closer to 200mW +/- depending on the lens you get. Yes then you can just get a host/heatsink kit like the Skyray host kit or similar and just connect the red and black from the module to the red and black from the host, set the module in the heatsink and screw the head on. Assembly should take under 5 minutes.:beer:
Here is the Skyray kit on ZL

Hey , My name is Gary I am from Oklahoma City. I just got my 2w I ordered from you the other day. Let me tell you it is a really nice piece I set it in the cree host I purchased when I bought a 1.7w from you several weeks ago. The orders were shipped under my bosses name, Jim Collins, ( I use his ebay account).
I just wanted to tell you thanks for such awesome products at such reasonable prices. I got into lasers a couple years ago and have been buying off Ebay out of China. Mainly 532nm green lasers 100-200mw then my last China purchase was a 532nm 400mw. The module was friggin' huge, almost 3" long and of coarse way under spec. just like the rest of them.
I had been looking into some of the U.S. turnkey stuff but most of it is way out of my price range. When I got the 1.7w from you and got it set up I was amazed at the performance, quality , and especially the price.
My next build I would like to build a 1w green hand held laser then maybe a 3-4w blue hand held laser.
Anyway thanks again and I will be in touch for my next build.
Gary Charlton.

Wow, ambitious. Unfortunately, both of those are not practical builds right now. A 1W green will set you back about $1,000 minimum, and for a 4 Watt you would need to construct a dual diode system.

3 watts of blue is possible though, with the Nichia 9mm diodes, which are also provided by DTR.

Hey thanks for the input. I am not up on what is feasible or even needed in a hand held laser, but it is an interesting hobby. Along with that keeping safety and responsibility in mind.

Trust me, there is a steep learning curve at the beginning, but after that, you retain all of the knowledge and you get the hang of it. Just make sure to get the need for safety in your head early on.

Your eyes are worth $40, don't you think? Get an eagle pair, or two, and "protect your seeing balls!" - styropyro

If you need anything, PM me.

DTR, I am really pleased with the 1.7w and 2.0w blue lasers. I put that extra lens I ordered with my 2w on the 1.7w and it is a much better set up than the 3 lens set up it came with. I see you have a 1.4w 520nm looks pretty good. What would it cost to get the driver, diode, and lens package for that? Im really interested in that one. Thanks, zapp.

Ok, I read up on the 1 w 520nm and I did a little research on the diode and I am impressed with its performance. All that said, cant afford one yet.
So, my next quest. Lead me toward the Menice. Thanks, zapp

These are the greatest lasers I have ever seen! I need to get busy...

I could not really find a place on PayPal (don't have an account) or his site for ratings but I would give DTR a 8 out of 5 rating for service. Will definitely order from him in future. Trusted retailer!

DTR: Do you have a review for the build in your signature? Is that actually cyan?

I ordered some of the 22mm heatsinks for the 12mm copper modules from DTR's site and was looking to find a simple "mechanical mod" to attach to the 510 thread adapter. I am looking for something that can use both 1x 18650 and 2x 18350 batteries(or just 2x 18350's) that has no voltage or wattage regulation. Simple, sleek designs with little or no branding are preferred. I checked sites like fasttech but many products are sold our or only use one type of battery.

Forget that - you're going to blow up laser diodes left right and centre without a driver. The reason that lasers generally use one type of battery are that a driver is easier to design for a smaller input voltage range (i.e. 3-4.5V instead of 3-9V).

Edit: I'm pretty sure that these 510 thread mods did exist - Jnrpop has a big collection that he posted a thread of fairly recently. I believe the diode drivers were in the removable part - so you could have multiple threaded modules each with a diode module assembly /w lens and driver. Not sure where you'd get something like that now other than making it yourself...

A Buck driver can accept either one or two batteries as long as the Vf of your laser diode is lower than a single Li-ion cell like a red diode. But, different diodes need different drivers and different cells as some require little current and others, quite a lot. If you are using a boost driver, you will want to limit your batteries to just one as two will exceed the Vf of your diode and you will blow your diode.
