Connecting Your Device to the ComboPak
A laser diode is very sensitive to electro-static discharge (ESD), over-voltage,
and over-current conditions. When connecting a laser to the
ComboPak
, make
sure proper ESD procedures are taken. In addition, it is critical that the proper
current limit and voltage limit be set for the laser diode. Exceeding the laser
diode’s rated current or voltage can damage or destroy the laser diode, and the
ComboPak
’s
hardware protection features can only protect the laser diode if
these limits are properly set.
The laser anode and cathode outputs are electrically isolated from ground, as
are the photodiode inputs.
A cable is required for both the TEC and Laser outputs. Arroyo Instruments
carries cables specifically designed for these applications, both with a DB
connector on the device end or with a bare wire pigtail for terminating the
connection into a custom mount or device:

CAUTION
The interlock connections must be kept isolated from all
other connections and from earth ground. Failure to do
so may damage the instrument.
NOTE
Connections to the
ComboPak
and the laser diode
fixture must be secure. Tighten any screws on the DB-9
connectors, and make sure all connections are in good
condition. Poor or intermittent connections can damage
or destroy the laser diode.
