Hi, i am going to make a 1 watt laser with these compenents:
Diode: 5.6mm 445nm ~1W laser diode [445nm] - $49.99 : Modwerx Shop
Driver: I am going to make my own, i will be putting two pots on so one will be the maximum mA and the second pot will come out of the housing so i can adjust the power to my choice.
Housing(very simple): 1591XX IP54 Transparent Blue Enclosures : Plastic Enclosures : Maplin
Batteries: 18650 3.7V Trustfire Protected Battery (2400mAh) - Detailed item view - OdicForce Lasers Online Shop
Heatsink: As the heatsink i am going to get a block of aluminium and fit it is the housing. I will then put the aixiz module in the heat sink.
Axiz: http://modwerx.com/shop/laser-module-w-heatsink-and-ar-coated-glass-lens-405450nm-p-60.html
I would be using 2 batteries which would make up 7.4v but it would still give me 2400mAh, by putting 2 batteries it would get me up to the required voltage which is 7.4v. I would still get 2400mAh as the current does not change.
Does this sound like a good idea? Has anyone got anything to correct me on, please say...
Thanks
Oh yes and i have a question
How many mA should i put into the diode, i heard that i should put 1.2A to get 1W. Am i right?
