Item to Inspect: 49541-2 - Newport / ILX Lightwave LDP-3811 Precision Pulsed Current Source

More Information

Newport / ILX Lightwave LDP-3811 Precision Pulsed Current Source Overview

Features:

  • DC and Precision Pulsed Current
  • Standard Trigger In and Out Functions
  • Settings Include Pulse Amplitude, Pulse Width and Pulse Repetition Interval
  • Pulse Overshoot Less than 5% Guaranteed
  • Low Noise Output Drives 50W
Model LDP-3811 is a microprocessor-controlled current source designed specifically to drive low power laser diodes. The unit operates in either stable continuous wave or precision pulsed mode and offers a dual range 200/500 mA output. An intuitive front panel makes it easy to adjust pulse amplitude, pulse width and repetition interval. Standard GPIB interface and flexible triggering offer complete system integration with other equipment in the lab, improving the ease and speed of data gathering and remote measurement.

Unlike many other pulsed current sources, the LDP-3811 has been designed to improve communication throughout the lab. The standard GPIB/IEEE-488.2 interface allows remote programming and readout from most computers. All instrument functions accessible from the front panel are also accessible through the interface bus.

The standard Trigger In/Trigger Out function is located on the rear panel. This feature provides the ability to trigger measurements from remote instruments, simplify data collection and certify accurate start and end points for pulse analysis.

The LDP-3811 offers a large range of adjustments designed to meet a wide variety of test parameters. Pulse amplitude and pulse widths can be set from 100 ns–1 ms, pulse repetition interval (PRI) from 1 µs to > 1 ms. A constant PRI mode permits adjustment of desired pulse width while maintaining PRI setting. In addition, the constant duty cycle mode allows maintenance of a preset duty cycle, regardless of how PRI or pulse width is adjusted. The intuitive front panel allows pulse characteristics to be set or changed easily. Operating modes are illuminated and informative fault indicators warn of potential damage to the laser diode.

The LDP-3811 minimizes pulse distortion by delivering an exceptionally clean pulse guaranteed to less than 5% overshoot. The unit’s low noise, transient-suppressed output is designed to drive 50 W.

The LDP-3811 also offers complete laser diode protection. Features like current limiting, overshoot minimization and transient protection have all been designed into the circuitry of the unit.

The ILX Lightwave LDP-3811 Precision Pulsed Current Source may still be available for purchase and support from Artisan Technology Group beyond End-Of-Life (EOL) by the manufacturer (OEM).

Precision Pulsed Current Source Price & Specs

Newport / ILX Lightwave LDP-3811 Precision Pulsed Current Source Description

Functions

Programmable precision pulsed current source delivering configurable current pulses with adjustable amplitude, width, repetition rate, and edge timing. Provides low-noise, high-stability output with remote-sense load regulation, fast rise/fall times, and programmable slew for clean transient responses. Includes triggering and synchronization options, programmable offset and ramping, and a defined output impedance to preserve current during load changes. Suitable for calibration, pulsed-power testing, device characterization, and measurement stabilization where accurate current pulses and repeatable duty cycles are required.
