Chapter 8. Diode replacement
‘click’ and cannot be removed from the connector when tugged. Re-
peat with cathode (black) wire crimp pairs. Reconnect the diode
connectors to the
PCB
underneath.
8. Test operation by reconnecting the controller and powering on the
TA
temperature controller first, check operation is normal with tempera-
ture approaching the set point, followed by powering on the current
controller at 100 mA. Referring to the test report table
Guide for seed
coupling at low and high tapered amplifier current
, set the
TA
diode
injection current to a value where you expect a few mW of
Unseeded
light and verify that some output light is visible on an IR viewing
card.
9. Restore the lens collimation (see Chapter 6) then follow the instruc-
tions for aligning either an internal seed laser (Chapter 4) or external
seed laser (see Chapter 5).
