Thorlabs LDC200C Series Laser Diode Controller Operation Manual
The Thorlabs LDC200C Series Laser Diode Controllers are high-accuracy, precise injection current controllers designed for laser diodes and LEDs. The series includes various models such as the LDC200CV for VCSELs, the LDC201CU for ultra-low noise applications, and models with enhanced compliance voltage for blue laser diodes. These controllers feature a 5-digit LED display and are operated via front panel UP-DOWN keys.

Questions answered in these manuals
What is the soft start function?
The soft start function protects the laser diode against undesired transients by smoothly increasing the injection current after switching the laser on.

How is the laser diode protected against open circuits?
If the connection to the laser is interrupted during operation, the output is switched off immediately and can be switched on manually only.
