Hi,
I am working on a current and temperature controller for low power diode lasers (<200 mA), and I need to make a test load to simulate them. I found some information and it seems the general idea is to use a resistor of known value (like 1 Ohm), and some diodes. Then you measure the voltage and calculate the current. My question is, how many diodes and what kind of diodes do I use? All the samples I find use different diodes and different quantities.
Thank you.
