Help with: driver, 2w 445nm laser and test load
Hello everyone,
sorry for my very very bad English ...
being I am new in the world of laser and having already burned one I would ask you kindly help:
I bought this laser:

thanks a lot for the support DTR, you're super nice ...
then I bought this driver:

Vladimir thousand thanks to you for the help ...
now I want to do a load test, and reading on the net I am not clear if and how many types of diodes I have to use
I have at home this material:
1N5404 Diode and Ω 5W Wirewound Resistor
my questions are:
1) the diodes can be go well and how many should I use?
2) someone has this driver and can help me set it up?
many thanks to everyone
Roberto

The 445nm laser diode will drop about 5V at max current, a 1N5404 drops about 0.8v AT 2a, so you'll need to put 6 of them in series to simulate the laser diode.
Not sure about the driver though, sorry.

Here is a pictorial schematic of the test load:

hello,
thank you for your reply and help ...
In fact, my question is about how much 1N5404 I need, from what I read in the web only 4 1N5404 and 6 1N4001
I am confused...
