Is "forward voltage" and "forward voltage drop" for a diode the same? I read where forward voltage is the min voltage to forward bias a diode so is this also the voltage drop across the diode? If so does this also apply to a diode laser? This is probably a dumb question.

Thanks all. That helped a lot.
The voltage drop across a diode will vary a small amount with the current going thru the diode Forward voltage and voltage drop tend to be used interchangeably
This applies to all types of diodes

Yes.
If you're concerned about forward voltage drop consult the manufacturer's graph of Vf vs If.

And very much more so with the junction temperature.
