Product Overview:

These laser diode drivers are an affordable bias current source for semiconductor lasers. They deliver a maximum output power up to 1.5 amps and up to 14 volts of compliance voltage. These OsTech drivers include a digital communication interface and are supplied with LabView drivers for easy set-up and control of your laser diode. An external modulation signal can be applied and these units will accept digital or analog modulation.

Protection Features for Safely Driving Your Laser Diode:
These modules offer many protection features to safely bias you laser. They have a slow-start current ramp to protect the laser during the power-on sequence. The current ramp is set to 300 milliseconds by default but can be adjusted by the user. The user can set a current limit. Additionally, on board transient filters protect the laser diode from harmful transients which can occur from brown out or black out power conditions. To protect the user, a safety interlock circuit is available for a fast shut-down under the interlock trigger conditions.

User Interface:
The user has the choice of using the standard RS232 serial interface on the rear panel or ordering the optional USB interface ($100). After connecting the driver to a PC, the LDC-164 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. In addition to CW mode, the LDC-164 includes an internal function generator which can be used to operate the laser diode in a QCW (pulsed) mode with user set pulsed 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.
