Laser Diode Control Unit

Key Features & Capabilities Modular Mainframe with Isolated Channels 4 independent channels with up to 8 isolated outputs for controlling multiple laser diodes Each module is electrically floating and fully isolated from all others to prevent damaging ground loops Independent power supply per channel provides protection and stability Wide Range of Plug-in Modules Current source modules: From 200 mA to 4 A (or up to 8 A) LD controller modules: From 200 mA to 2 A with integrated 12 W TEC control TEC-only modules: Up to 32 W with voltage measurement Modules accept thermistor, IC, and RTD temperature sensors Laser Current Source Performance Current setpoint resolution down to 10 μA on low-current ranges Compliance voltage: Up to 8 V per channel Low-noise architecture with ripple levels down to 1 μA in filtered CW mode Operating modes: Constant current (low/high bandwidth) and constant optical power External analog modulation input (0–10 V) for high-speed current modulation up to 500 kHz Photodiode measurement circuit with adjustable reverse bias for back-facet monitor diodes
