output circuit is earth-grounded at some point (such as through the laser package
and/or mount), the user must be careful to avoid multiple earth grounds in the
circuit.
Figure 3.1 shows the configurations of connecting laser diodes and photodiodes
with the LDX-36000 Series High Power Current Source.

Laser Current Source Output

For the LDX-36000 Series models, the current source output connector is either a
combination D 9W4 connector on models with less than 50A output (CW), Figure
3.2, or high current terminals on models with more than 50A output (CW), Figure
3.3. Laser voltage, photocurrent, and temperature measurement functions are
accomplished through a separate DB-0 connector labeled "Sense" directly above
the high current output connector.

Connections for General Operation
Note: Cable connections to the laser must be secure. Loose connections may cause
momentary open circuits which can damage the laser by generating damaging high
voltages and currents.
