Models AF3 and AF3-1 are Solid State Amplifiers having a wide bandwidth of 5 Hz
to 250 kHz and 1 MHz respectively. The 650 volt (AF3) and 350 volt (AF3-1)
maximum peak to peak output voltages can drive light modulators having a capacitance
of up to 150 picofarads.
These AC coupled amplifiers provide a DC voltage bias for setting the modulator
optical operating point. They are intended for driving the relatively low capacitance of
Lasermetrics Low Voltage Modulators as well as other available transverse field and
reduced voltage devices. Applications include: Broadband Audio and Ultrasonic
communications, Light Chopping and Gating, Data Printing, Polarization and
Optical Control systems employing lasers.
The Model AF3-1 provides four times the bandwidth at more than half the output
voltage of the AF3. These amplifiers were designed for use with Lasermetrics Series
3079 Low Voltage Light Modulators and can be used with similar low voltage light
modulators from other suppliers.
