Good morning,
New guy here and this is my first post.
I am in the process of building a test platform for my laser experiments. I have a 1.5 amp constant current driver on order (Meridith Instruments) and plan to add digital metering for output voltage as well as output current. I will be removing the board mounted pot and installing a 10 turn pot externally to adjust the current.
In the paperwork that came with another driver I built, the manufacturer said to never try to measure the output current on a CC driver. They say it will destroy the laser diode. I am trying to figure out how metering the current of the LD could damage it. I am an engineer by trade and measure current all the time.Is there something about a LD that is different than other electronic devices such that you can't measure its current?
Sorry for the dumb question. :thinking:
