Product Overview:

15 Amp Precision Laser Diode Driver

The LDC-483 laser diode driver is an affordable bias current source for semiconductor lasers, and includes industry-leading safety features to protect the laser diode across a wide range of operating conditions. The driver delivers a maximum output power up to 15 amps and up to 12 volts of compliance voltage, optimized for pump laser diodes.

Protection Features for High Power Laser Diodes

The driver includes laser diode protection features such as current limit, soft start current ramp, and power surge filters to make sure that your laser diodes are protected at all times. The soft-start current ramp is pre-set at the factory to 300 milliseconds, but is user-adjustable. This current ramp-up and ramp-down function is designed to protect the laser from thermal shock during power-up and power-down sequences.

Modulation, Internal Function Generator, and QCW Pulse Modes

In addition to CW mode, the LDC-483 includes an internal function generator which can be used to operate the laser diode in a QCW (pulsed) mode with user-set pulse width from 15 microseconds to CW. The rear panel d-SUB connector has dedicated pins for an external modulation function generator to be applied to the bias current driving the laser.

TEC Controller:

The integrated 150 watt TEC controller is a full P.I.D. loop controller based on a precision output current and voltage driver. The current and voltage source is designed for stable control of a Peltier cooler. They work with multiple temperature sensor types and utilize and H-bridge topology to drive the Peltier element for optimum laser temperature stability.

User Interface:

The user has the choice of using the standard RS232 serial interface on the rear panel, or ordering the optional USB interface. After connecting the driver to a PC, the LDC-483 includes LabView drivers with a simple to use graphical user interface (GUI). All of the laser diode control parameters can be set and monitored using the GUI, including bias current set-point, current limit, slow-start current ramp time, and modulation. If the user does not have LabView, a serial command set is provided in the manual for the user to control the driver.
