Product Overview:

These high power laser diode drivers with high compliance voltage are designed to precisely and safely bias multi-single emitter lasers. They are also optimized to control multiple devices in series mode. They offer a high compliance voltage CW mode of operation as well as a QCW mode of operation. In QCW mode, they have a pulsed width range of 25 microseconds to CW. These units have fully featured front panel and also can be controlled by RS232 or with USB (optional). They are offered with LabVIEW drivers and full GUI interface. They are designed to accurately and safely driver multi-emitters from companies such as nLight, Lumentum and II-IV. They will source the voltage required to bias the laser at a constant current set point.

Driver Features Specifically for High Compliance Voltage Lasers:
These current drivers operate from a standard AC power plug with a universal power supply that accepts 100 VAC to 230 VAC, 50/60 Hz. They accept both analog and digital modulation with a frequency range of DC to 50 kHz. While they operate with a modulation signal from an external function generator in your lab, they also come with anQCW internal function generator. The internal pulse generator for QCW mode of operation can run in continuous, single and pulse burst modes from an internal or an external trigger. The LDC-157 also comes with an additional current source dedicated to biasing a red pilot laser as well as a 12V, 800 mA supply to power an external fan. These features add to the unit's multiple driver capabilities designed specifically for high voltage and high power devices. They will measure a photo diode current with a range of 0 ~ 700 uA.
