What would you put into this?

I have the laser pointer host pictured below...and I want to build a blue laser out of it. This will be my first laser build. I Know what I need to put into it...but I don't quite get the details yet.
I believe that this is the same as the host I have...
Adaptable Host for 12mm Laser Modules - Detailed item view - OdicForce Lasers Online Shop
I have a diode on the way in a blu-ray sled....and that's about it. I know I need the module, and a driver with a spring contact and push button on it.
My question is...What would you put into this laser host if you were to build a blue laser pointer...and where would you get them from?

What did you plan to set the driver to? That host won't handle the heat if you push it past 100-200mW.

As for what else you would need, you didn't mention a diode press. You will need that to get the diode into the module. You also need a lens.

I would put an Osram PL450 diode into that host, if i was to go blue. You can get it Here, either as a bare diode (will need module and press), or already pressed in copper module, with leads. He also has a couple of lens options. You can even get diode w/driver, then you can just install the module.

Check the link in my signature to see my build with this diode. It's regarded as the best for a small blue, would be nice for that host.

I made a 1.4W laser using that host with a boost driver and single 18650 battery.

A lower power version using a ready made module (which I initially used) would also work but won't be focusable and would need two 16340 cells for power.

Thanks for all the replies. I would rather build a blue laser, but I can fall back on a green one if I need to. I still need to collect some parts as well. I'll have to check out all the links.

This link here:1.4W 450nm
Will get you a better version of the chinese module linked above. It's also cheaper, and not from china.
You could get it's little brother from the same site and have a good single mode (ends in a dot, not a bar) laser with a tighter beam and better run time.

When I just saw this thread I was half temped to say "you don't want to know"... I won't say that though. :p

BTW, I would go with a green module for that host. I wouldn't want to put too much power into it since it wouldn't handle heat all that well.

Please post back with some pics when you have built it :)

well what about the blue modules from dx 100mW 405nm Blue-Violet/Royal Purple Laser Module (3V) - Free Shipping - DealExtreme
Anyone had any experiance with them?
Never owned one but I'm looking at it for a cheap blue build. They have different mw 405 as well. Now I gota go get some blue glasses.
You most probably will need a heatsink to fit the host measure that first.
Eudaimonium made me a heat sink for $10 was extremely happy send him your specs.

I would get the 5mW violet module from fasttech. Pman got one and metered it at 87mW

I'll post pix when I get it made. I like the idea of a 100-200mw blue setup. Maybe the over spec fasttech module will work...
Sorry I took so long to reply....works been crazyness....

Oh, it handles heat quite well in mine. At least for the first 150 secs. :p

A 1.4W 445nm isn't all that bad on heat generation. You get the real heat when you start to approach 2W.

Also, even if it doesn't feel very hot it may be that the heat isn't being conducted to the outside of the host very well. That would mean the diode is getting quite a bit hotter than you know and could kill it much faster. I just would not advise a 2min+ duty cycle. That host flat out does not have enough heat sinking ability for that to be a long term laser.

AFAIK, FastTech only has 405nm(Violet) and 532nm(Green) modules. You are probably best off with one of their 532nm modules since 405nm is barely visible and IMO isn't much fun until you hit about 500mW.
THIS is the 532nm module I have that runs at 110mW.

Hmmmmmm.....not fun till 500mW huh? Well that kinda blows a hole in my plan. How powerful of a blue laser do you need for it to be easily seen in a dim room (Not pitch black)?
