The ThorLabs TLD001 T-Cube Laser Diode Driver is a compact instrument for precise control of laser diodes and LEDs across laboratory and research environments. Operating in constant current or constant power modes, it delivers up to 200 mA with 10 µA resolution and supports analog modulation via ±10 V input. The unit features a 5-digit display, front-panel adjustment potentiometer, and safety enable key switch for manual operation, alongside full USB control via included Kinesis® software and legacy APT™ packages. An interlock facility and 14-bit measurement resolution ensure reliable laser protection and accuracy. Measuring 120 mm × 60 mm × 47 mm, it mounts directly to optical tables and integrates with K-Cube™ Controller Hubs and the TTC001 TEC controller. Temperature stability is <70 ppm/°C typical, with laser diode current noise 8 V
