Hi.:yh:
No laser driver around has "modes" as far as I know.
I'd like to build my laser with modes.
I have tested several LED drivers for 445nm LD from cheap sites as DealExtreme, KaiDomain.
And I found a proper 445nm LD driver for one Li-ion.
http://www.kaidomain.com/ProductDetails.aspx?ProductID=1672#
I think the following driver is the same one, but it is "back-order" state.
DealExtreme: $4.26 3W 19-Mode Universal Regulated Circuit Board for Flashlights
The board is marked as "NJG-18".
With my custom test load( 4x 1N540x, 1ohm) and one 18650, I set the potentiometer of the board, the current is:
50mA-400mA-1200mA
After building with my custom laser P60 module and aixiz 445nm lens, the power of A140 is:
70mW-350mW-1160mW
Unlike the explanation, it has 3 mode. Low-Med-High. No strobe mode.
Awesome! It is really 3 mode laser!
I can't understand the mismatch of power-current of the low mode.
I guess there was an error in the calculation of test load at low mode or I didn't understand the charateristics of 445nm LD....
But I am happy to have 3-mode laser and low mode is visible unlike my expectation.

ps)It is hard time for me to wait "v6".....
