First off, Hi to all in the community! =)
this is my first posting. I'm an undergrad physics student.
I am currently working on a new diode laser system design, the output frequency of the laser is dependent on the length of the external cavity.A piezo crystal is attached to a semireflective mirror whose position determines the length of the external cavity. By feeding the triangle wave to the piezo I can scan across a very fine range of output frequencies. Specifically frequencies corresponding to electronic transition structures in rubidium atoms whose spectrum is being used for other applications such a frequency locking and stabilaztion etc.
The shape of the input signal is important since any irregular deviations such as non linearity in the gain will translate directly a shift in the laser output light frequency, so I need to preserve the shape of the triangle wave in the output.
I need to build a high voltage amplifier that is, I need to turn an input signal(sawtooth 0 to 10 V pk to pk) from a function generator into an output signal : 0 to 100 V peak to peak at maximum gain.I also need a gain adjustment knob.the frequency range is from 10 Hz to 5 kHz and the load is a piezoelectric transducer with a capacitance of 0.09 micro farads (

I'm sort of a noob in circuit development and I'm in desperate need of suggestions and advice! Currently I'm planning on achieving this by using an HV opamp such as **broken link removed** but i'm not sure if that is the best choice. I'm planning on setting a basic non inverting configuration and again I'm not sure if thats the best design. I have attached a copy of the schematic. Please let me know if what I've drawn is correct. Any suggestions or advice is greatly appreciated..

Also after some searching I found this:
**broken link removed**
I'm not sure if it could be used for my application. If anyone has had any experience using these your advice is much appreciated.
