Help with making a 405nm Laser

Laik · Jan 22, 2013

Hi this is my first post and I'm looking to get into lasers. The only one i have built is a 50mW green, but all i had to do was solder a spring onto a module then put it in a pen/pointer host. Anyway here is my plan:
Extract the diode from this: 803T HD DVD DRIVE LASER LENS PHR for xbox360 xbox 360 | eBay
and put it in an Aixiz housing and solder longer leads on and then but the back of the housing on. Then buy this driver: 3-5V Power Supply Driver for 5-100mw 405nm Violet/Blue Laser Diode Module | eBay
and solder the wires off the diode onto the driver and then glue it to the back of the aixiz housing. Then to top it off i will bypass the switch and put it in this housing: Torch Style Host For 12x60mm Laser Module w/h 405nm Glass Focus Lens/DIY Host | eBay

What i need to know:
1. Will it work?
2. Will it fit (be the overall size of a normal module)?
3. If so, which pins do i connect to the driver (positive and negative or positive and case because the housing uses its self to conduct the positive)?

I have a beutiful picture i made in paint of what im going to do to make the complete module type thing... ish

Thank You

I'll try and answer your questions as best as I can.

1) Yes it will work... you'll get laser light from this driver in combo with the PHR diode (Xbox blue-ray)
2) Will the drive fit in the module... hmmm well it might be a snug fit. Looks to be the right size
3) Hooking up the diode to the module. You'll notice that the driver has two solder pads on the top of the driver, and one underneath.
The pad underneath is case pin/unused. The top two are the + - of the LD. + being closest to J106 - being closest pad to R6.

You'll need extra heat sinking in a host. Please DON'T run it without. The host you posted I don't think will work with the O-like modules.
( Someone correct me if I am indeed incorrect). They should have a 12mm dia hole to fit the aixiz module. If not then, the host has it's own
press fit sink already. My guess is the latter as this host is used by o-like.
Do some more research. You're heading in the right direction.

GET SOME safety glasses for 445nm/405nm. One mistake with a laser like you're building and you can do instant eye damage!

I mean i am going to solder longer leads to the diode that will bareley come out of the back when it is screwed on and then solder those wire to the driver and when i say will it fit, i mean will tho whole thing (module) fit into the host? I might even use this host because you only need the 'bushiness end' which is at the bottom of the brass where the diode sits and then its the driver board, the front end of the aixiz housing is like the bottom of a normal module, so if i use this host all i have to do is put the diode in the aixiz housing, solder the driver to it and then press it into the heatsink of the host http://tinyurl.com/a6yw3pu
Thank you very much for a reply though

Nope.. You don't do that with this driver. If you look, you'll see that this driver is used for a pen host. The diode is pressed into the Aixiz sink and then the driver is attached to the diode pins directly. No wires needed.
My concern is that this host you intend on using is shoddy. I think it has it's own sink in which case you're
not going to get a Aixiz module in there.
Use a flashlight host instead.

That's what i intend on doing now in this host DIY/Test Laser Torcstlye Hosts/For 12x60mm Laser Module | eBay
The host will conduct the positive to the module and the negative will go through the spring. Sorry if i sound like im trying to prove you wrong, im just trying to understand this.
Thank You

Yep, that'll do.
That host is appropriate for what you're building.

Thanks, but what pins do i solder to the driver (green laser diodes have a different pin configuration to red, and red is different to blue, aren't they?)

Say what?
I explained how to hook your driver up several posts ago.
Now, I'm going to warn you that other members here will call
my post as spoon feeding noobs. Please research before
making a laser or posting. This site has a great search tool.
I'd make use of it.

Sorry if this comes across a rude, but I am letting you know that
People can and do get neg rep for asking for basic searchable
info.
Look at the post I made about the driver.

Laik · Jan 23, 2013

Okay, thanks. I understand as well, getting so many newbies asking the same question does get really annoying (i have been in the same position but not with lasers.) Someone had to let me know, but now i know and i can become better. Just to clear it up, i just needed to know what pin whas what (what is + what is -) but it's fine, ill search it

Thank You

Wow.... i didn't see where u told me how to solder it, i'm so sorry. i feel like such an idiot :cryyy:
Thank you for everything

Please read the post next time. You are new here. You are still learning about how the forum works.
I get it. Cheer up.

Just I have to make sure you understand that not everyone is going to be noob friendly.
Some people on here can get quite impatient with new members and neg rep.
I really hope you'll make use of our very useful search tool. It works well.
IF you have have a question that is beyond what the search can deliver then ask for assistance. The driver you're using to be fair isn't one that we'd use typically. Some of our members here make their own boost drivers and sell them.
Look in the Pro shop. Build some reputation before buying from there.
Welcome to the forum. Enjoy.

Completely changed my plan now. So im gonna use the c6 host from survival laser (with a purple heat sink to match my phr diode

) and im going to use 2x RCR123's which will output 8.4V fully charged because the phr uses about 9V, doesn't it? and i need a small driver board so i have found one that can handle multiple batteries with the total of up to 12V. I just need the final okay from a more experienced member, i don't want to stuff anything up.

C6 Host: Survival Laser C6 Host Assembly
Driver: http://hacylon.case.edu/ebay/laser_diode/Groove_2.php

Edit: How do i get the negative to the circuit board, i know it travels through the case, but am i supposed to solder the negative to the brass ring around the board?

Don't make the same mistake I did. RCR123s are not the same as 16340s. Fully charged RCR123s, which may not even be Lithium-based, produce 3.0v each. 16340s produce 3.7v. Yes, the latter being Li is fully charged at 4.2v, but either way it may not matter when driving an LD washing through a driver.
