8. Diode replacement
Replacement tapered amplifier diodes can be purchased from
MOGL
abs
or directly from suppliers (e.g. Eagleyard Photonics or Coherent). The
diode is provided in an industry-standard C-mount package, which is then
mounted to a proprietary
MOGL
abs
MGM-068
mount (fig. 8.1).

ture side. Cathode pin, groove for cathode wire, and one registration pin hole are
on the right.
To replace the diode, ensure the controller is off and head cables discon-
nected, then follow these steps:
1. Open the
PCB
cover plate underneath the chassis and disconnect the
diode anode and cathode wires at the
PCB
. The diode connectors are
labelled on the
PCB
. If the diode connectors are laying flat on the
PCB
(Hirose), lever the connectors up gently from the wire entry end
of the connector. If the diode connectors are standing upright from
the
PCB
(JST), gently tilt the connector towards the tall side of the
socket, then pull the connector up (see fig. 8.2).
2. Remove the crimp terminals from the connectors by gently levering
up the plastic tabs (see fig. 8.3) using a sharp/pointed tool, then
slide the crimped wires out of the connector. When reinserting crimp
