Designed to compliment ILX Lightwave’s line of precisionlaser diode instrumentation, the LDX-3100 and LDT-5100 offer
precise low-noise, high-stability current and temperature controlof laser diodes to meet the needs of critical OEM and other spaceconstrained applications.
The LDX-3100 laser diode current source provides theflexibility of a mountable circuit board with laboratory-grade
performance and proven laser protection. It can be operated
in constant current or constant power modes. Similarly, theLDT-5100 thermoelectric temperature controller provides
outstanding temperature stabilization of laser diodes orphotodetectors.
The products can be used together or independently and areeasily incorporated into other products with demanding laser
diode drive requirements. Both are based on ILX Lightwave’s
proven circuit topologies, and are pin-compatible with ILX
Lightwave laboratory instruments and laser mounts.

BOARD LEVEL CURRENT CONTROL

monitor is used in a feedback control loop to the laser
drive current to maintain stable laser output power,
even if temperature changes.

The LDX-3100 Current Source is a board level device
which, when powered by the appropriate supply,
delivers stable, low noise current. The LDX-3100
is optimized to drive laser diodes and LEDs withan output range of 0 to 250 mA, with a compliancevoltage >5.5V.

PROVEN ILX PERFORMANCE
The circuit topology of the LDX-3100 Laser Diode
Current Source is based on ILX’s LDX-3412 Current
Source, which is designed for laboratory benchtop
applications. For more information about the
LDX-3412, contact a sales engineer at ILX Lightwave.

TWO OPERATING MODES FORFLEXIBILITY

For more information about laser diodes and driving
them safely, please download the following Application
Notes from www.ilxlightwave.com.

The LDX-3100 can be operated in one of two modes.
In constant current mode, a stable current can be
adjusted from an on-board trimpot or through anexternal control voltage. The output can be modulated
up to 2 kHz, so it’s easy to dither the laser current
and power and wavelength tuning. In constant powermode, the photocurrent from the laser’s rear-facet
