Pulser amplitude feedback amplifier

Purpose

The pulse generator built by Alex Barnes and Jon Kulakofsky produces -10V pulses of duration 1ns fwhm. These pulses are split 90:10 at the output of the pulse generator circuit, and driven out two coaxial cables. The -1V signal matches expectations for a NIM logic signal, and is fed into a discriminator to generate a trigger for the data acquisition. The coaxial cable carrying the -9V pulse is coupled directly from the coax cable conductors to the pins of a laser diode of type DL3148-025 - 635 nm, 5 mW, Ø5.6 mm. The data sheet for the laser diode shows the following pin-out for the SOT23 package.
