CHAPTER 4
4. Laser Diode Driver Module Operation
4.1 Laser Diode Driver Module
4.1.1 Introduction
The 6500 Series laser modules are precision current source modules for use in the
6000 Modular Controller.
Features of the 6500 Series include:
• Service-free modularity (calibration information is stored on the module)
• Closed-case calibration
• High-stability, low noise design
• Flexible setup with 6000 Save/Recall front panel functions
• Photodiode feedback control mode
• Modulation input
• Fault detection
• Current and voltage limiting
• Special Configuration for MOPA Lasers (65xxM modules)
4.1.2 Installation
This section describes the procedures for installing and removing a module from the
6000.
NOTE
The save/recall bin information will be lost upon detecting
any change in the module configuration (such as installing
a new module).
CAUTION
Although ESD (electrostatic discharge) protection is
designed into the module, operation in a static-fee work
area is recommended.
CAUTION
Do not plug in or unplug a module with
the AC power on.
