Well to abtain that speed you need BUCKS!!

The only way to get modulation at that speed commercialy is with an
Acoustic Optic (AO)..
This uses a crystal vibrated to create a standing wave from the input beam.
This can effectivly be pulsed at 500khz (I am not quite shure on the fig.)
One drawback is that this method waste power....
What is your Application?
I might be able to help you more if I knew what it was....
