Connecting to the ComboSource
A laser diode is very sensitive to electro-static discharge (ESD), over-voltage,
and over-current conditions. When connecting a laser to the
ComboSource
,
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
ComboSource’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. In addition, the photodiode inputs are optically
isolated from the laser outputs, ensuring complete electrical isolation of the drive
circuit and photodiode measurement circuit.
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:
Function
DB to DB p/n
DB to Pigtail p/n
Laser
1220B
1221B
TEC
1260B
1261B
TEC w/ remote sense
1262B 1263B
The 1262B or 1263B cables are only
needed if you will be operating the
ComboSource
with an RTD sensor
and
using the 4-wire sensor connection.
Otherwise, the 1260B or 1261B cables are sufficient.
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
ComboSource
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.
