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:
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?

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
