Enhanced Protection Features for the Laser Diodeįor optimal LD protection, the LDC4000 Series offers a set of enhanced protection features.
7.3 injector driver module feedback signal generator#
The integrated pulse generator can be triggered internally with an adjustable repetition rate or externally via a BNC jack at the rear of the unit. The LDC4020 is at ease providing sharp and accurate 100 µs pulses of 20 A peak current without any unwanted overshoots. The LDC4000 Series can be operated in continuous wave (CW) or quasi-CW (QCW) mode. Continuous Wave (CW) or Quasi-Continuous Wave (QCW) Operation Both monitor inputs can be calibrated by a sensor response parameter to directly display the optical power in milliwatts. Instead of bare thermopile sensors, sensor amplifiers or power meters with analog voltage output can be connected here as well. The thermopile input provides four ranges: 10 mV, 100 mV, 1 V, or 10 V maximum voltage. An adjustable-bias voltage can be applied to the photodiode to improve the linearity. The photodiode input provides two ranges: 2 mA or 20 mA maximum current. The LDC4000 Series allows the user to select photodiodes or thermopiles as the sensor for monitoring the laser diode power output. short 100 µs Pulse of 20.0 A generated by the LDC4020 in QCW mode Photodiode and Thermopile Monitor Input This temperature stability is required for applications like diode laser wavelength tuning and atomic absorption cell spectroscopy.įigure: Oscilloscope screenshot of a typ. When combined with our TEC laser mounts, the TED4015 can achieve a thermal stability of 0.001 ☌.

To order this service, scroll to the bottom of the page and select Item # CAL-LDC4.įor more information about the constant current and constant power modes, the photodiode and thermopile monitor inputs, the continuous wave (CW) or quasi-continuous wave (QCW) operation and the enhanced protection features for the laser diodes please see the More Info tab.įor driver software, as well as programming reference guides for Standard Commands for the Programmable Instruments (SCPI) standard, LabVIEW™, Visual C++, Visual C#, and Visual Basic, please see the Software tab. These features, together with the new design, which offers silent and efficient operation, make the LDC4000 Series Laser Diode Controllers an ideal choice for most applications. Thorlabs recommends recalibrating these controllers every 24 months and offers a factory recalibration service. A higher setting resolution and measurement resolution is offered via remote control.Ĭompared to the LDC200C Series, the LDC4000 Series offers higher injection currents as well as additional features like the Quasi-Continuous Wave (QCW) operation mode, an internal modulation generator, a thermopile input, laser voltage measurement, and an optical power limit. Additionally, the LDC4000 Series can be fully remote controlled via an SCPI compatible USB Interface.

See the Display Screens tab for some examples. The series is designed for stand-alone operation and is controlled via front panel keys and intuitive operation menus on a large and easy-to-read graphic LC display. This series supports all laser diode and monitor diode pin configurations and features a constant current or constant power mode. The LDC4000 Series of Laser Diode Current Controllers provide precise and stable current for driving high-power laser diodes with injection currents up to 20 A.
