ILX LIGHTWAVE LDC-3900 4-Ch Modular Laser Diode Controller

The ILX Lightwave LDC-3900 Modular Laser Diode Controller features four channels with eight isolated outputs for controlling multiple laser diodes. Modules include current sources, these modules also feature a photodiode measurement circuit for devices with backfacet monitor photodiode and analog modulation up to 500kHz for dithering the laser current for wavelength tuning. Five different current source modules up to 8A can be driven in any one of the following modes: Constant current, low bandwidth; Constant current, high bandwidth; Constant optical power. TE (thermoelectric) controller modules with up to 32W of power and voltage measurement. TEC modules accept thermistor, IC and RTD temperature sensors. A low noise, biopolar output with TE voltage measurement and an ultra-stable topology achieves stabilities better than 0.005°C. Controller modules combine a current source with a temperature controller in one module. Laser current from 200mA to 2A is available with an integrated 12W temperature controller for current and temperature control of laser diodes.. An independent power supply powers each channel, providing protection and stability for your laser diode. Standard GPIB IEEE interface.

*This is a Web introductory price for one calibration of the ILX LIGHTWAVE LDC-3900. Price does not in most cases include measurement performance data. Pricing does include NIST traceable calibration and issue of a calibration certificate and calibration label. Pricing may vary slightly due to volume and location of laboratory supporting calibration. Volume pricing may apply. On-site fees may apply depending on logistics, location and volume of work to be completed during the visit.

Related Optical Terms and Definitions. For a complete list go to our  Terms and Definitions Page.

A change in the optical frequency caused by direct modulation of the laser. A chirp is a signal in which the frequency increases ('up-chirp') or decreases ('down-chirp') with time. In some sources, the term chirp is used interchangeably with sweep signal.

The extent to which optical power from one signal path is prevented from reaching another signal path.

Polarization Extinction Ratio
Polarization Extinction Ratio is the ratio of optical power in the slow axis of the polarization maintaining fiber to optical power in the fast axis within a specified wavelength range.

Sidemode Suppression Ratio
Sidemode Suppression Ratio is the ratio of average signal power to the optical power of the highest sidemode within a distance from 0.1 to 6 GHz to the signal’s optical frequency, expressed in dB.

Wavelength Stability
Wavelength Stability is the change of wavelength during given time span, expressed as ± half the span between the maximum and the minimum of all actual wavelengths.
