Properties
The laser current driver LDD100 from Artifex Engineering employs a digitally programmable analogue end stage for flexible and accurate current control. Currents of up to 600A with pulse durations of 150ns to 3s are generated with fast rise and fall times of 70ns (F-version) or 600ns (XL-version) – essentially a laser driver without overshoot. Due to the flexibility in setup and control, this diode led driver is practical for many laboratory applications. For automated measurements, the unit may be directly controlled via the USB interface. Alternatively, all parameters may be input via the graphical software or via the integrated keypad and OLED display.
FIELDS OF APPLICATION
Applications include testing laser diodes and in laser diode characterization (LIV measurements, etc.), general lab use and for OEMs. The LDD100 is a laser diode driver, made in Germany, that generates fast and very square current pulses and is very simple to operate. Artifex Engineering supports this product with a custom strip line configurations service.

What is the LDD100 used for?
The LDD100 is a precision current source designed to drive laser diodes safely and accurately.
Why is a specialized laser diode driver required?
Laser diodes are extremely sensitive to current spikes and require stable low-noise current sources.
What current range does the LDD100 support?
The current range depends on the configuration but is suitable for typical laser diode testing.
Does the driver support current limiting?
Current limits protect the laser diode from damage.
If we aim to maximize the output current, what is the highest achievable current (is it possible to exceed 600A)? Can multiple units be connected in parallel?
Currently our limit with the LDD100 is 600A and units not able to be connected in parallel.
How do I connect a laser diode to the LDD100?
The laser diode is connected via the output terminals with proper polarity. Basic cards available upon request for custom connection configurations.
Can the LDD100 operate in pulsed mode?
All configurations support pulsed operation for thermal management and characterization.
Does the driver include monitoring outputs?
A monitoring BNC output allow observation of current and voltage during operation.
