Newport 5600 Series - Connecting to Your Laser

22 Chapter 3 Laser Diode Driver Operation
3.4 Connecting to Your Laser
When connecting laser diodes and other sensitive devices to the driver, we
recommend that the 5600 be powered-up and the laser output be off. In this
condition, a low impedance shunt is active across the output terminals. When
disconnecting devices, it is only necessary to turn the laser output off.
Pins 3 and 4 of the LD connector are the negative output, and pins 1 and 2
are the positive output current connections. These pins are jumpered to
provide greater contact area for the output connection.
NOTE
Whenever external connections are made to the
output at pins 1 and 2, and 3 and 4, these
connector leads should be jumpered to ensure the
greatest laser diode safety.
We also recommend the use of the mating connector for your interface rather
than binding posts, or loose wires. This will insure the best connection.
NOTE
Special cabling is required to preserve the pulse
transition time and overshoot. Newport
recommends the 5600-02 or 5600-04.
3.4.1 Laser Diode Connections and Shielding
CAUTION
Before connecting the laser diode to the unit, be
sure that the
ENABLE
key switch is in the OFF
position. Before turning on the laser output, be
sure that the current limit and voltage compliance
limit has been correctly set.
