Has anyone built a laser part by part and customized one? if anyone has it would be greatly appreciated if they would offer a little help. Thank you /ubbthreads/images/graemlins/help.gif



Very sorry... I am interested in building a DPSS 500mW 808nm 40mW-ish with a cystal from. http://www.casix.com/product/Laser_DPM.htm I have emailed them for a quote on the high powered crystal.
 
Your question is too open ended. Are you building a solid state laser, a gas laser, visible, IR, ...?
 
if i remember talking to you correctly superman, you wanted to build a dpss laser correct? im pretty interested in this too, but its gonna be a little more costly than you think, and certainly not as easy. id be interested in working on this project with you; sharing ideas, links, how to's, manufacturers/suppliers, etc. ill do some searching and you do the same for the guy who built a laser into a small black box on here... its really cool. im not sure if it was made from scratch, or just put in a new casing, but that would be where to start.
 
Depending on the type, wavelength, etc.. I'm also working on making an 80-100mw laser. I'm using the 9mm 500mw 808nm diodes, etc... And I've got someone who is making aluminum casings, and the driverboard would be very similar to the leadlight ones but based on AA batteries.

If you want to chat, I'm on MSN and AIM -

heres what enigmahack has come up with so far:

i emailed dwight finney of IFIXLASERS and he said that he could make the driver board for us, and he should be sending a quote soon.
 
i have come up with something for the casing that will help with the heating... but i think this will have to be professionally milled (shouldnt be a problem to find someone to do it)... i know someone infact with a metal shop that might help us... i will ask him tomorrow... anyway:

Instead of 500mW...... what about one of these? Or no good?
 
enigma and i talked it over online, and he mentioned a diode and heatsink assembly from bostom laser co. that has a max output of 2w. with the custom driver board from dwight, 3-500mw shouldnt be an issue at all. my concern though, is that the 8x AA batteries will not be able to power the unit for hardly any amount of time.
 
well everyone with a PGL-III, what kind of runtime are you getting from 2xC batteries?

Also, what kind of 8xAA battery configuration are you planning? 8xAA all in in serial for 12 Volts, or 8xAA with 4 pairs of AAs in serial (like 4AA-to-D adapters) for 3 volts.
 
we'd be using a continous stream - 12V DC - we'd be using a peltier element, fan and diode being powered from that. The current draws from the individual parts is quite minimal, so more than likely the 8AA batteries would work best that this point. *that and they're small enough that they'd work*

"Instead of 500mW...... what about one of these? Or no good? "

Those would be PERFECT provided we weren't concerned with the thing overheating. Actually it would be awesome to be honest, but my true concern is how expensive are those going to be to acquire on a constant basis. It's cool to spend 50-60$ on 1 diode once, but that will jack up the price considerably if this became a "production" thing.

*not saying that it will be, but I always want to consider my options*

Also, I DO have someone in metal/machining that would be more than capable of creating the cases. Not an issue at all.

I'll probably order 2 or 3 500mw diodes and also 2 or 3 1.2W diodes and check the difference. I'll also contact the distributor of the 1.2W diodes and see what they're able to do for us.

My other small concern was that the distrubitor of the 9mm 500mw diodes I have here, well is here in canada. that means no duties, very very cheap shipping, and very short shipping times as well. This means a LOT when you're in the process of getting a few of them.

In any case, I'll consider this all and probably order a few from each and test the quality as well as durability from each manafacturer and end cost. More than likely, the 1.2W diodes will be well worth it in the end, but I want to make absolutely sure.
 
Aluminium for the casing is a must...it's lightweight and is the best for heat dissipation. If you can, mount the diode also on a copper plate that is fused to the walls of the casing with thermal grease.

Copper is good for conducting the heat away from the source very quickly whereas the aluminium fins does the rest.

It's the same for processor heatsinks with a copper core.

Good case design... /ubbthreads/images/graemlins/thumbsup.gif
 
Count me in if you decide to make this a production run. I've got most of the parts already together but have been struggling with the mounts for the optics... cool work!

enigmahack and i have been in contact about all of this on aim. my case design will be used in the final product and be slid into another, sleek casing (which im having anodized)... he is handling the rest of it though..
 
Hi, i am new here and my english is very bad (I am from Austria)!
I also want to make my own Laser. At first i try to use a 2 Watt 808 nm diode in a TO-3 Case from RoithnerLaser, but i can't find a Driverboard who can give 2,64A to the diode. So i ordered a 1Watt model and the biggest Driverboard which i found can make max. 1,2A and operating Current of the diode is 1,4A so i can't use it with full power. It take the cristals from a Leadlight (i hope it's not to much Power for this).
As Heatsink i use a big one for TO-3 case with a temperature controlled fan. the Power for this came from a small rechargable lead Batterie 6V 4Ah
Do you think it will work ?
 
lol theres no way... youre going to need casix... what you are describing, Arni, is the plan that we already have, you just described the pictures i posted... come on we need some more ideas here!
 
But the high-Power Cristals on the Casix page can handle max. only a 500mW Diode. Can this work?.
Did i need some Lenses befor and after the cristals.
