The LDC-3900 Series Modular Laser Diode Controllers features 4, 8 or 16 channels with up to 32 isolated outputs for controlling multiple laser diodes. Modules include current sources with maximum outputs from 200mA to 8A, TE (thermoelectric) controller modules with up to 48W of power and voltage measurement, and controller modules with laser control from 200mA to 2A and integrated 12W TE control.
An independent power supply powers each channel, providing protection and stability for your laser diode. Every module incorporates low noise, high stability performance, and ILX Lightwave’s unmatched laser diode protection topologies including independent current limits and laser diode shorting relays.
Remote communication through an IEEE/GPIB interface simplifies testing and control of multiple devices. LabVIEW® drivers are also available for any combination of mainframe
and module.
Wide Range of Modules
Five current source modules and five combination modules along with two TE controller only modules make the LDC-3900-120V configurable for many laser diode testing and control applications. Each module is electrically floating or fully isolated from all other modules. This allows you to configure your laser diode test system without the worry of potential laser diode damaging ground loops.
Current Source Modules
The LDC-3900-120V current source design offers superior laser protection and low noise, high stability performance. These modules also features a photo-diode 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
Highly Stable Temperature Control
The LDC-3900 Series TEC modules control temperature of your devices with 32W of power. These TEC modules offer maximum flexibility with a choice of operating modes and temperature sensors covering thermistors, IC, and RTDs. A low noise, biopolar output with TE voltage measurement and an ultra-stable topology achieves stabilities better than 0.005°C. A smart integrator control loop, programmable from the front panel or through GPIB, delivers fast settling times.
Controller Modules
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. All of the features found in the current only and temperature control modules are incorporated into these flexible modules and include multiple modes of operation, external modulation, a choice of temperature sensors, and all protection features.
Intuitive Front Panel
Divided into two sections, TEC and LASER, the front panel offers quick, easy operation and information display without confusing multi-layer menus. Each channel is directly addressable from the front panel “adjust” section and indicated through discrete LEDs next to the respective display. Laser and TEC parameters and modes are easily selected or adjusted through discrete push buttons.
Powerful GPIB Interface
For automated control, the IEEE/GPIB interface allows programming and readout from most computers. All instrument and module functions are accessible through the interface allowing you to simultaneously control multiple laser diodes from the same address. For virtual instrument programming, LabVIEW® drivers are available.
