Hello, i'm new with lasers, i've a green 200mw that a I bought a long time ago, and now i'd like to have a 250mw blue laser inside a AA Minimag. I think the power source can be 2x 14500 7,4v battery from DealExtreme.

I saw in ebay this module with a drive from geareb:
250mW+ 405nm High Power Blue-Violet Laser Diode Module - eBay (item 280507873408 end time May-23-10 08:40:47 PDT)

Look this specs that have in the page:

Code: 
You are bidding on a precision new Single Mode Blu-ray blue violet laser diode module.
Laser diodes are rated for Class IIIb 250mW @405-410nm CW extract from never used Blu-Ray RW Pickup.
This diode died after  414mW@350mA 10mA step I-P-V test - room temperature with glass lens after install tiny heatsink.
This module include tiny heatsink (glass lens not included). 
It is possible order 405nm AR coated glass lens as optional part($17).


Max Output : With tiny heat sink (200mW @ 180mA, 250mW@ 230mA, 300mW@ 270mA, 350mW@ 300mA, 414mW@ 350mA)
 I recommand less than 30 sec duty for 200-300mW drive eventhough
 it's work 40 minutes continuously with a tiny heatsink and 2:40 with 2 tiny heatsink at 250mW.
 Or this module need more heatsink than a tiny heatsink for more long work.
Recommand Output : 200mW@ 180mA(tiny heatsink) - Tested with 405nm AR coated lens
Threshold Current : ~33mA(~3.6V)
Operation Voltage :  ~5.0V @ 180mA
Module : 12mm diameter x 30mm length with acrylic lens 
                  Lead wire 30cm(Red plus[+], Black minus[-]) with 2.5mm pitch Connector.
DIY Kit : 9 component, 320mA max limit

I'm from Brazil, sorry for my bad english, but what battery I'll use to power my laser? With 2x 14650 (7,4v) or 2x AA (3.0V) battery?

I would stick with the 2x14650,because they will last longer when you will use your laser.If the driver doesn't work directly with that voltage(if works with lower voltage...),then you can use one N400x diode in series with the driver power line.Or when you find out the voltage that the driver works with,you can use a voltage regulator L7805 for 5 volts,L7806 for 6 volts ect.Probably you will not need any of the above,though.
I don't know much about this kit,but I think the 2x14650's voltage should be just fine.not sure though.you have to read the manual that probably comes with the kit....

that driver is essentially the same as the rkcstr just alot bigger. so your choice of hosts is very small. most likely a box. also for running a lot of current you will want as much mah as possible. so that is something for you to think about. read this for refference....http://laserpointerforums.com/f38/prh-10440-rkcstr-time-test-51005.html . Also, your module, as it states in the listing, it does not come with a lense. and it seems as if it was tested with an 405nm AR coated lense. and those are a little pricey. so you probably won't get the 250mw as stated.

The seller is highly reputable and I would recommend Gearab, Also known as Lee(ee), Kiok. Good guy to deal with.

MAKE SURE YOU GET A GOOD HEATSINK with that module. The diode in the module is a 6x diode. It gets piping hot in that style of host. I would ask to change the host to a black lab style host with heat fins. I have a red 300-350mW LOC from this guy and it is an awsome unit, handles heat well.

I think that I found a best way to do this laser.

If I use one Micro BoostDrive with a 300mw + 405nm diode, think that will be better in a AA Maglite, if I power with 2x 1,5v AA battery I think that I can have a nice result.

What do you think about this?

Bye

Well.....you SHOULD get a confirmed good diode, from HighTechDealz, but I guess it's your money. And using 2x AA batteries will get you nowhere, you'll need to get some of the protected batteries, like 10440's I believe. But that's not what I'm good at, so ask somebody else. I just know that you won't be able to use 2x AA batteries, you will only get 3V. Also, for a maglite you need a flexdrive, you can get a flexdrive from that same site. And...you're right on the aixiz module, you need that, but buy them from hightechdealz they're like $2.50 or somthing like that, a lot cheaper than that ebay thing.

And since you really want this, go to this link and then contact Jayrob about buying this kit, and get the hot option it will all cost about $155 (~$110 for the kit and hot option, ~$45 for the diode), but atleast you know it'll work. You need the hot option because I'm going to assume you don't know how to set the current on a driver, so the 'hot' option is for you. He includes a flexdrive, AND sets it at the current you want (you want 200mA), all you have to do is solder on a module and you're ready to roll! ;)

A good diode:

It's even pressed into the module for you, so you don't have to do it ;)

Have fun!

:pYeah,3 volts are good for red diodes but not for 405nm violet.You should have minimum 3x1,5 volts(3xAAA or 3xAA) AND Microboost Drive.Aim for something bigger considering energy.Protected batteries are the batteries that they include a a small pcb that protects them from overheating during use or recharging,short circuits and rapid discharging.Protected batteries have minor or not at all "memory" issues.......

Probably it is a SF AW 210.I work a lot with them....It looks like them...And yes,no more than 180mA...If you want to last a bit more...170mA and glass lens

I know now that probably i will get in trouble....
Why everybody likes those Aixiz modules?
Comparing IN REAL LIFE with other housings ....my God they suck!
I'm really sorry if i sound offensive but ...OK they are cheap...And yes you can find them very easy in bulk quantities.....But they still suck....

Take a look a housing that surpasses many other housings (Tested 100%)

405nm laser module housing w/glasses lens [OL1845-BL] - $12.99 : Welcome to O-Like.com, Your source for laser products

This housing is just a product,nevertheless from who made it,that stands out from the rest....:D:D:D

True for the "heatsinking" capability and stability, but keep in mind that the hosting tubes for the AAA batteries are almost all 12mm inside diameter ..... more easy to build one using an Aixiz module, in this case .....

And, after all, they are on the market from more time ..... this count something too ;)

Yes,I guess you are right...
Anyway,I 'm making violet laser pointers,using bigger hosts,so size was never trouble...but they are from really tough aluminium alloy,the diode secures by screw ring so you can replace very easy,they have cooling fins-and they make good job keeping the heat down,glass lenses (interchangeable with 405-G1 without any mod) ect...ect....
