The LDD100 employs a digitally programmable analogue end stage for flexible and accurate current control. Currents of up to 400A with pulse durations of 2µs to 3s are generated with rise and fall times of 500ns – essentially without overshoot. Due to the flexibility in setup and control, the LDD100 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 LCD display.

FIELDS OF APPLICATION

Applications include laser diode characterization (LIV measurements, etc.), general lab use and for OEMs.

The LDD100 from Artifex Engineering 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.

Speed/Pulse duration: fast rise time models, long pulse models

Maximum output current: any value from 1A to 400A

Custom strip line connectors.

Can I use the LDD100 for LIV testing of laser diodes?

Yes. The LDD100 is preconfigured for selection of staircases of current pulses. The user sets the minimum and maximum current required as well as the number of currents to generate in the staircase.

Can I set a bias current for soft pulsing of laser diodes?

Yes. The LDD100 allows up to 1A of bias current.
