How do I power a laser diode taken from a laser pointer?
I have a laser diode from a laser pointer and I want to power it, but I have no clue how to do so. Can anyone help?

You need to know the required current and, depending on the circuitry you use, the required voltage.
You can use a transistor to give it the proper current, but this requires knowledge in electrical engineering. This method requires only the required current.
Otherwise, you can use a resistor to set the current with the diode’s voltage drop. This method required knowing both the voltage AND the current.
