The LDC-3900 Modular Laser Diode Controller features

four channels with eight isolated outputs for controlling

multiple laser diodes. Modules include current sources with

maximum outputs from 200mA to 8A, TE (thermoelectric)

controller modules with up to 32W of power and voltage

measurement, and controller modules with laser control

from 200mA to 2A and integrated 12W TE control.

An independent power supply powers each channel,

providing protection and stability for your laser diode. Every

module incorporates low noise, high stability performance,

and ILX Lightwave’s unmatched laser diode protection

topologies including independent current limits and laser

diode shorting relays.

Remote communication through an IEEE/GPIB interface

simplifi es testing and control of multiple devices. LabVIEW

drivers are also available for any combination of mainframe

and module.

Wide Range of Modules

Five current source modules and fi ve combi-

nation modules along with two TE controller only

modules make the LDC-3900 confi gurable for many

laser diode testing and control

applications. Each module is

electrically fl oating or fully iso-

lated from all other modules.

This allows you to confi gure your

laser diode test system without

the worry of potential laser diode

damaging ground loops.

Current Source
Modules

The LDC-3900 current source

design offers superior laser

protection and low noise, high

stability performance. These

modules also feature a photo-

diode measurement circuit for

devices with backfacet monitor

photodiode and analog modulation up to 500kHz

for dithering the laser current for wavelength tuning.

Five different current source modules up to 8A can

be driven in any one of the following modes:

1) Constant current, low bandwidth

2) Constant current, high bandwidth

3) Constant optical power

Up to four modules can be easily
adjusted and controlled from the
LDC-3900 front panel.

Highly Stable Temperature Control

The LDC-3900 TEC modules control tempera-

ture of your devices with 32W of power. These TEC

modules offer maximum fl exibility with a choice

of operating modes and temperature sensors

covering thermistors, IC, and RTDs. A low noise,

biopolar output with TE voltage measurement and

an ultra-stable topology achieves stabilities better

than 0.005°C. A smart integrator control loop, pro-

grammable from the front panel or through GPIB,

delivers fast settling times.

and temperature control of laser diodes. All of the

features found in the current only and temperature

control modules are incorporated into these fl exible

modules and include multiple modes of operation,

external modulation, a choice

of temperature sensors, and all

protection features.

Intuitive Front Panel

Divided into two sections, TEC

and LASER, the front panel offers

quick, easy operation and infor-

mation display without confusing

multi-layer menus. Each channel is

directly addressable from the front

panel “adjust” section and indi-

cated through discrete LEDs next

to the respective display. Laser

and TEC parameters and modes

are easily selected or adjusted

through discrete pushbuttons.

Powerful GPIB Interface
For automated control, the

IEEE/GPIB interface allows programming and

readout from most computers. All instrument

and module functions are accessible through the

interface allowing you to simultaneously control

multiple laser diodes from the same address.

For virtual instrument programming, LabVIEW

drivers are available upon request or through the

ILX website.

* Semiconductor lasers are sensitive devices. Always
take appropriate antistatic precautions and use extreme
care when handling laser diodes. For more information,
request ILX Application Note #3, “Protecting Your Laser
Diode.”

Controller Modules

Controller modules combine a current source

with a temperature controller in one module. Laser

current from 200mA to 2A is available with an

integrated 12W temperature controller for current

COMBINATION MODULES NOTES:

1 All values measured after a one-hour warm-up period.
2 Over any one-hour period, half-scale output.
3 Over any 24-hour period, half-scale output.
4 Measured from resulting intensity fl uctuations of a laser diode,
measured optically with a 150kHz bandwidth photo detector.
Measurements made with 1MHz detector are typically 10%
higher.
5 ILX Lightwave model LNF-320 low-noise fi lter option may be
used if lower noise performance is required.
6 Maximum output current transient resulting from normal
operational situations (e.g., power on-off), as well as accidental
situations (e.g., power line plug removal). For more information
request ILX "Transient Test Standards" #LDC-00196.
7 Maximum output current transient resulting from a 1000V
power line transient spike. Tested to ILX Lightwave
Technical Standard #LDC-00196.
8 Maximum monitor photodiode current drift over any 30-minute
period. Constant-power mode stability specifi cation assumes
zero drift in detector responsivity.
9 Output current rated into a 1Ω load.

10 Measured at 25°C.
11 Software limits of range.
12 Accuracy fi gures quoted for a 10kΩ thermistor. Accuracy fi g­ ures are relative to calibration standard. Both resolution and
accuracy are dependent on the user-defi ned confi guration of
the instrument.
13 Over any one-hour period at 25°C. Short-term temperature
stability is a strong function of the thermal environment of the
thermistor and TE module. Room air currents in particular can
easily cause fl uctuations of 0.1°C in an exposed mounting con­ fi guration.
14 Over any 24-hour period at 25°C.

In keeping with our commitment to continuing improvement, ILX Lightwave
reserves the right to change specifi cations without notice and without liability for
such changes.
