The LDX-3232 High Compliance Laser Diode Current
Source is the industry’s only laser diode driver specically
developed for controlling high compliance voltage devices
such as quantum cascade laser diodes. Careful attention to
design allows these drivers to deliver up to 4A of low noise
current at up to 15V with a stability of better than 20ppm. This
performance is critical for development of room temperature
quantum cascade lasers and spectroscopic applications using
quantum cascade lasers. This new current source joins ILX
Lightwave’s LDX-3200 Series Laser Diode Drivers, which are
known throughout the industry for their reliability, precision,
and ease-of-use.
In addition to precision current control, the LDX-3232 is
loaded with standard features such as dual current ranges,
constant power control, ne/coarse setpoint control, laser
current and voltage measurement, photodiode current display
modes, forward voltage adjustment and measurement, and an
external modulation input.
Furthermore, all of ILX Lightwave’s proven laser diode
protection strategies have been designed into each model
including slow start, adjustable current limits and compliance
voltage, intermittent contact protection, and shorting relays.
In addition, the LDX-3232 accepts a TTL input that can be
congured to turn off the output to the laser diode in an overtemperature condition.

All values relate to a one-hour warm-up period at room temperature, 25°C.
Based on resolution of digital-to-analog converters used in circuit.
Over any one-hour period, half-scale output.
Over any 24-hour period, half-scale output.
Measured electrically with a 1 load at half scale output; evaluating spectral noise density over a
150kHz bandwidth from 125kHz to 275kHz.
Maximum output current transient resulting from normal operational situations (e.g., power on-off,
current on-off), as well as accidental situations (e.g., power line plug removal).
Maximum output current transient resulting from a 1000V power-line transient spike. Tested to ILX
Lightwave Technical Standard #LDC-00196.
Maximum monitor photodiode current drift over any 30-minute period. Assumes
zero drift in photodiode responsivity.
50% modulation at mid-scale output. Higher bandwidth is possible with smaller
magnitude modulation signal.
TTL low input will disable the current source output.
Similar resolution available over GPIB.
The responsivity value is user-dened and is used to calculate the optical power.
Four-wire voltage measurement at the load. Voltage measurement accuracy while
driving calibration load. Accuracy is dependent upon load and cable used.
In keeping with our commitment to continuing improvement, ILX Lightwave reserves the right to change
specications without notice or liability for such changes.
