This chapter describes the electrical configuration and mounting of laser diodes.
The LDM-4616 features pin configuration headers (terminal blocks) for each socket
within the mount. These headers allow various laser pin-outs to be used. It is extremely
important that you verify that the configurations of the headers are correct for your laser
types (pin-outs). Incorrect wiring of these headers may result in failure or damage to the
laser devices. Before instally your lasers, refer to the instructions below for details on
how to correctly configure your mount. The LDM-4616DFB has a fixed pin configuration.
For the LDM-4616DFB version, verify that your laser pins match the fixed pin-out.
Connecting the LDM-4616 Mount to a Laser Diode Controller
The LDM-4616 Laser Diode Mount electrical connectors are compatible with
current sources and temperature controllers manufactured by ILX Lightwave
when standard ILX Lightwave cables are used. The 9-pin D-sub connectors have
standard ILX Lightwave pin-outs. If you are using any other laser driver, use
extreme caution when connecting the cables from the mount to the driver. Check
the pin-outs of the laser driver and temperature controller for compatibility with this
mount before connecting the mount.
Note that ILX Lightwave current sources employ a system interlock feature, in
compliance with Federal CDRH requirements. The interlock pins 1 and 2 on ILX
Lightwave current sources must be connected together before current can flow
from the source. ILX Lightwave's Model CC305S interconnect cable contains a
jumper between these two pins and therefore no special action is necessary if this
cable is used.
Proper shielding of the current source and temperature controller signals is
necessary to ensure proper low-noise performance and immunity to radiated
transients. Based on findings from laboratory testing at ILX Lightwave, we have
