ThorLabs TLD001 T-Cube Laser Diode Driver

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 LD current setting resolution: 10 µA LD power setting resolution: 1 µW LD current/power measurement resolution: 10 µA (14-bit) Temperature drift: <70 ppm/°C (typical) LD current noise: <3 µA RMS (typical) Modulation input range: −10 V to +10 V Operating modes: Constant current, constant power Key Features Manual control via 5-digit display, mode button, laser on button, and safety key switch Adjustable current limit via front-panel key slot USB interface (Mini-B to Type A cable included) with PC-based control Analog control input for modulation Interlock facility for system safety Compact 120 mm × 60 mm × 47 mm footprint Typical Applications Laser diode and LED precision control in laboratory and research settings requiring stable, reliable operation with accurate current or power regulation. Compatibility & Integration T-Cube family member compatible with APT™ Controllers. Works with TTC001 TEC controller, K-Cube™ Controller Hubs (KCH301, KCH601), and Thorlabs laser diode mounts (LDM21, LM14S2). Power supply sold separately; TPS002 supports up to two T-Cubes. Includes Kinesis® software and ActiveX® programming interfaces.
