What's available these days for generating well-defined pulses with
really sharp rise times?

We use the SY part to generate fiducial pulses in a biggish laser
modulator. What's cool is that it has a diff ecl/cml input, diff high
current outputs, and you can smoothly adjust the output amplitude from
zero to max. And max is pretty big.

And they only cost about $7.
