M5000 High Voltage Linear Differential Amplifier

Very high voltage linear amplifier for driving Pockels cells

This 5000V series linear amplifier has been designed to drive large aperture electro optic modulators. It consists of two 0.4 - 3.0 kV linear amplifiers that together produce a differential output that can be connected to either side of the modulator. This produces an optical phase change equivalent to the output from a single sided 5000V unit.

The amplifier has a bandwidth of 14KHz and a rise time of less than 5Ás.

It incorporates a 1 - 10KHz internal oscillator giving sinusoidal, triangular and square waveforms. For square wave modulation applications the positive and negative excursions of the square wave output can be precisely controlled. This differential drive technique increases the lifetime of the modulator by maintaining a zero mean voltage across its terminals.
