Product Overview:
The LDD-1121 is an innovative pulsed laser diode driver that contains a specialized current source able to precisely drive laser diodes in continuous / modulated and pulsed or mixed operation. It is equipped with optional laser power measurement circuitry (photodiode input), the LDD-1121- LPC can also be operated as a Laser Power Controller.
The LDD-1121 is fully digitally controlled. Its firmware is upgradeable to offer various communication options and to meet specific customer requirements. Current, laser power [LPC option] and temperature measurement hardware can be calibrated. For basic applications or device evaluation, only a power supply and a laser diode need to be connected to it.
This device can operate stand-alone in current control mode. Internal generators (on board) allow for parametric definition of flexible output waveforms. It has included PC-Software (USB / RS485) that facilitates configuration, control, monitoring and live diagnosis of the LDD. Current and laser diode pulsed driver power [LPC option] charting is also available from within the software.
The LDD-1121 is part of the LDD-Family of Meerstetter laser diode drivers, which are designed to operate alongside devices of the TEC-Family of Peltier controllers. Both families of drivers share the same system bus protocol, design concept, and technology. It may be fully controlled by a system bus that features RS485 communication, pulse driver, interlock and 6 reserve lines.
