For troubleshooting, the proper laser driver (found beneath the AG network analyzer) was connected.
The current ~1mA was provided and the driver detected the "open circuit", which means the laser diode was busted.

The laser diode in the parts list is: "GTRAN GaAs Strained QW Laser Diode, Part # LD-1060".
