Sample and hold circuit for Q Switch Laser

[Galsaba]

Anyone can refer me to where I can see a schematic diagram of the above?

Thanks,

Joe

Yes, for the light.
I will have a power detector that will convert the laser energy to a
pulse of voltage, and I will need a Sample and Hold Circuit to measure
it.

A peakdetector with a a bandwidth of 1GHz or so.
Basically an amplifier, then a low capacity
diode to a cap and a jfet amp.
The build geometry is more difficult than the schematic.
