I was sent the following message and since I could not help the person with
some factual or first-hand information I asked if I could post his question 
to this list.  Maybe someone here can help him. Note: send the reply to him
directly at [EMAIL PROTECTED]  but if you want to include the list that is ok
too. Your answer may help educate us all!! _______________ andrew davidhazy

Subject: light polarization

I am interested in shutter capabilities in the 4MHz region.  During a
search I happenned to come across your webpage that discusses Kerr Cell
shutters.  I am having trouble imagining this device.  Are there any
pictures you could send me or any pointers to schematics.  I'm also
interested in how to use lower voltage to create the Kerr effect.
Creating 20000V pulses at 0.25us intervals seems like a very daunting
task.

Thanks,

Stuart
