Laser diode controller

The LDC2000 is a high-precision, laboratory-style laser diode controller designed for safe and simple operation of laser diodes and LEDs with drive currents up to 2A. When paired with the Thorlabs TEC2000 temperature controller, it can precisely regulate the laser current, optical output power, and temperature of the connected laser diode, ensuring stable operation as an optical transmitter.Key Features & Specifications:Current Control & Performance:Control Range: 0 to ±2 A (continuous)Compliance Voltage: > 4 VResolution: < 5 μAAccuracy: 100 μANoise (10 Hz to 10 MHz, RMS): < 20 μARipple (50 Hz, RMS): < 5 μA (typical)Drift (30 min, 0 to 10 Hz): < 200 μA (typical)Temperature Coefficient: < 50 ppm/°COperating Modes:Constant Current (CC) Mode: For precise current regulationConstant Power (CP) Mode: For regulating optical output power using a built-in monitor photodiodeContinuous Wave (CW) & Quasi-Continuous Wave (QCW) Modes: The QCW pulse width ranges from 100 μs to 1 s, with a repetition frequency from 1 ms to 5 s (0.2 Hz to 1 kHz)Modulation Capabilities:Analog Control Input Modulation: Supports external analog modulationModulation Coefficient (CC): 200 mA/V3 dB Bandwidth: DC to 50 kHzBuilt-in Waveform Modulation: Includes sine, square, and triangle wave modulation functions
